Catch transients in durability with high-speed sampling - Dual Capture

To visualize long term trends in durability testing and other situations, data is typically acquired at low-speed sample rates. On the other hand, suddenly-occurring transitional phenomena should be captured at high-speed sample rates.

The "Dual Capture" feature resolves these conflicting requirements by recording at two different sampling rates.
  1. DL850 Dual Capture 1

    Zoom Waveform - You can record up to 5,000 phenomena of high speed trigger measurements (up to 100 MS/s) at a record length of 5-500 kPoints while taking trend measurements at up to 100 kS/s.

  2. Event Waveform -Displays the timing at which high speed "sub" waveforms are acquired

  3. Low Speed Main Waveform - Max: 100 kS/s Trend waveform displayed in a low-speed Roll mode

  4. Capture Waveform - Max 100 MS/s Capture transients with high speed trigger measurement

DL850 Chattering 1

Example: Parts Durability Testing

Parts used in automobiles and other transportation vehicles must be highly reliable. The "Dual Capture" function is very effective when performing vibration testing of connectors under varying temperatures.

  • Chattering is accurately captured at high-speed sampling
  • Check the frequency of occurence at low-speed sampling

Recall Past Waveforms - History Function

When you spot an abnormal phenomenon during repetitive high speed measurements, often the anomaly has disappeared from the screen by the time you press Stop.

Always active, the "History" function automatically divides the long memory into up to 5,000 "history waveforms" that can be redisplayed at any time.

 DL850 EX7 2
To extract abnormal waveformsArrow
DL850 EX8 1

Searching history waveforms
When you want to extract abnormal phenomena exclusively, you can perform condition-based searches of the history waveforms. You can create a rectangular zone on screen and extract only waveforms that pass through or do not pass through the zone. You can also extract data based on amplitude and other parameters. 

To check the history...
DL850 EX9
You can display all past waveforms, and view a list of acquisition times at min 1µs resolution

Key Point
The History function requires no action during measurement. You can recall data at any time after measurement has been completed. Once waveforms have been recalled, you can zoom locations of interest or perform parameter measurements.

Armed with an array of trigger functions

Simple & Enhanced Triggers

The DL offers easy-to-use "Simple" triggers, or lets you combine various "Enhanced" triggers for even more advanced capturing.

Enhanced trigger conditions are set up intuitively in advanced, easy-to-understand graphical user interface

DL850 EX10

 

  • Edge: Trigger on a single trigger source condition (rising, falling, rising/falling)
  • Time: Trigger at a specified time or fixed interval
Enchanced
  • A -> B(N): Trigger when condition B is true N times after condition A becomes true
  • A Delay B: After condition A becomes true, trigger the first time condition B becomes true after a set time has passed
  • Edge On A: Trigger on an OR condition of an edge trigger while the A trigger is true.
  • OR: Trigger if at least one trigger condition of multiple trigger sources is true
  • AND: Trigger if all trigger conditions of multiple trigger sources are true
  • Period: Trigger when a condition regarding the waveform period becomes true
  • Pulse Width: Trigger on a condition relating a pulse width condition being true with a specified time width condition.
  • Wave Window: Trigger when the signal passes outside of an real time template "Wave Window"
Example: "A Delay B" trigger setup screen (GUI)

 

Wave Window Trigger

The Wave Window trigger is useful for diagnosing typical power supply troubles such as momentary loss, sags, and surges. It can also detect frequency changes, voltage drops, and other phenomena, with support for AC waveforms of 40 to 1,000 Hz. A reference waveform (Real time template) is compared with the current waveform, and a trigger activates if the current waveform falls outside of the allowable range. The reference waveform is generated automatically from the previous waveform in real time.

DL850 EX11

*The Wave Window is not displayed on the display.

Action ON Trigger

To capture infrequently occurring phenomena, you can use an "Action ON Trigger" to perform multiple actions that are specified in advance when a trigger occurs.

DL850 EX12 1
You can specify "e-mail transmission" for immediate notification in a remote location when a phenomenon occurs.
  • Beep Sounds
  • Prints out screenshots
  • Saves waveform data
  • Saves Screenshots
  • Sends e-mails to a specified address

Superior Noise Rejection

DL850 EX16 1Excellent noise rejection performance is achieved through meticulous low-noise design. Floating voltage switching waveforms in inverter circuits can also be captured with precision.

DL850 EX15 1
Model 701250 Voltage Input Module

Processes Noise Rejection and Executes Power Computations in Real Time - Realtime Math (/G3 option)

The DL850 is armed with a dedicated DSP (digital signal processor) for computations that enables between-channel math during waveform capture. These between-channel computations are powerful because they can be set up separately from fi lter computations. In addition to FIR, IIR, Gauss, and moving average digital fi lters, you can use maximum 35 equations such as arithmetic with coefficients, integrals and differentials, and higher-order equations.

  • Display any combination of measured and math waveforms (up to 16 total).
  • You can assign channels without modules.
Example: 3-Phase Power Computation
Power is calculated as the integral of the product of voltage and current over time (an average based on the period). Using the Realtime Math function, you can display 3-phase 4-wire power waveforms in real time. DL850 EX17 1

DL850 EX18 1


Key Point
Computations occur in real time even when in Roll mode. Computed waveforms can also be used to activate triggers.
Any vacant slots (CHs) can be utilized for the realtime math defi nition. Consequently, precomputation waveform and postcomputation waveform can be displyed simultaneously.

A wealth of functions gets you right to the waveform you want - User Defined Computation (/G2 option)

The DL comes standard with arithmetic, time shift, FFT, and other computations that enable you to display waveforms with offsets and skew corrections. And with user defi ned computations (/G2 option), you can create equations using a combination of differentials and integrals, digital fi lters, and a wealth of other functions.

User Defined Computation Setup Screen

DL850 EX21

Example: Amplitude Analysis Using FFT
With the User Defi ned Computation function(option) included, you can perform various-types of FFT analysis using two FFT windows. In applications such as vibration and shock tests, you can easily evaluate abnormal vibrations while simultaneously measuring other signals. DL850 EX22 1

Key Point
You can assign a log scale to the frequency axis.

Automatically extract waveform amplitude, frequency, and other parameters - Waveform parameter and statistical computation

Extract and display up to 32 parameters (amplitude, frequency, etc. including delay) simultaneously. Menus can be shown as lists of easy-to-read icons.

Statistical Computation  
The DL can automatically extract cycle waveforms and find the standard deviation and other statistics. Computations can be performed on history waveforms as well. DL850 EX23

Detect Abnormal Waveforms, Notify Users, and Determine Pass/Fail - Go/NO-GO Determination

The DL can determine whether waveforms or computed values of waveform parameters meet (GO) or do not meet (NO-GO) conditions that are specifi ed in advance. Upon judgment of the measured results, a pre-set action is performed and users are notified that an abnormal waveform was observed, along with the pass/fail
determination. This is a very useful function for such things as studying signals from manufacturing lines of electronic devices and tracing abnormal phenomena.

Example: Evaluating Motor Startup Characteristics 
DL850 EX24 1 Parameter measurement is taken of the time until reaching a reference RPM after motor start, and the subsequent GO/NO-GO (pass/fail) determination is made.

Synchronize Multiple Units Performing Simultaneous Measurements - IRIG input (/C20 option)

Unit IRIG Synchronized measurement across multiple DL850 units is made possible by inputting an IRIG time code signal.* The DL850/ DL850V's internal clock is also synchronized (locked) to the IRIG signal. Therefore, timing comparisons are highly precise even when continuously recording over long periods of time.
Key Point
You can make periodic observations remotely by connecting commercially available GPS receivers that have IRIG output and using the Time Trigger function.

Example: Synchronous measurements for large transport vehicles Simultaneously measuring both tips of airplane wings, or between railroad cars requires synchronizing multiple measuring instruments in time. With a single IRIG cable, the acquisition time of all data is made the same.

DL850 EX25

*IRIG (Inter-Range Instrumentation Group) started as an American military standard, and is now used in data recorders in the aerospace industry. The carrier frequency is a 1 kHz/10 kHz ASK (amplitude shift keying) modulating signal with a synchronizing precision of as high as 1 µs. DL850 support formats: A002, B002, A132, B122

The Flexibility of an External Hard Drive - External Hard Drive Interface (/HD0 option)

With an external hard drive interface, you can connect a commercially available eSATA standard hard drive. The DL can record to an external drive in real time just like it can with the built-in hard drive. After saving waveforms, you can switch the DL850/DL850V from the PC to the external drive and use the waveform data immediately.  Unit ESATA

Key Point
  1. Ensures Security  - Simply remove the drive after measurement to protect data. Or, keep restricted data only at the measurement site.
  2. Increases Capacity - If the external hard drive becomes full, you can simply switch to a new one (requires a restart).
  3. Hi-Speed Data Transfer - A data can be transfered at high speed between a PC and a hard drive.
* The external hard drive is an option when specifying the internal hard drive.
* The speed of realtime hard drive saving depends on the performance of the hard drive.

Check the Relationship between Hysteresis and Phase - XY Display Function

You can confirm the relationship between two signals using the X-Y display. This can be applied to measurements such as the phase angle of two sine waves.

You can select four combinations on the X and Y axes, and therefore display multiple X-Y waveforms simultaneously and find relationships between them.

Simultaneous observation of X-Y waveforms and normal T-Y waveforms (waveform display using voltage and time axes) is also possible.

Example: Computing dynamic BH characteristics of a magnetic substance On the DL850 you can measure voltage and current, then analyze hysteresis of magnetic flux density B and magnetic field strength H. Energy loss generated by magnetostriction can be evaluated by measuring dynamic BH characteristics.

DL850 EX26 2

Magnetic flux density: B = Integ (C1) / (K1*K2)
Magnetic field strength: H = C2*K1 / K3
C1: voltage, C2: current
K1: number of turns, K2: cross sectional area
K3: magnetic circuit length

Snapshots

With the push of "SNAP SHOT" key, you can save a "snapshot" of the measured waveform (the waveform displayed on screen). The waveform remains saved even if you restart measurement, therefore you can easily compare the snapshot with any newly measured waveforms. Snapshots can also be saved and loaded as files.
DL850 EX27
You can compare waveforms from varied conditions
Example: Comparison of a snapshot waveform (white) with another waveform

Web Server

DL850 EX28
You can operate controls and acquire screen images with a Web browser - no special software required on the PC.
The Web Server function displays the screen of any networked DL850/DL850V on a PC via Ethernet. From this screen, you can remotely start or stop measurement, update the DL's display, and take snapshots (capture images) of the screens.

Multilanguage Support

DL850 EX28 Adhesive front panel key label sheets ("panel sheets") are available in eight different languages. Multilanguage support is also provided for menus and error messages.

Saving Screen Images and Displaying Thumbnails

DL850 EX30
Screen images saved to storage media are shown on screen as thumbnails for easy identification.

Screen images can be saved to a specifi ed storage medium in PNG, JPEG, or BMP format. These screen images can be imported into reports or other PC-created documents.

Enhanced capabilities for vehicle design and development such as CAN & LIN Buses monitoring

DL850V 1

The DL850V ScopeCorder Vehicle Edition can display CAN- and/or LIN-protocol communication data as trend waveforms on the display by using the CAN Bus Monitor Module (720240) or CAN & LIN Bus Monitor Module (720241(*1) ). It can also trigger on decoded waveforms. By identifying the correlation between communication data on the vehicle-installed LAN and analog data such as voltage, temperature, and sensor signals or the ECU’s control logic signal, a vehicle’s overall LAN system can be evaluated. Furthermore, with the /DC option, the DL850V can be driven by DC power such as the vehicle’s battery, in addition to ordinary AC power.

(*1): The CAN & LIN Bus Monitor Module (model: 720241) is supported by the main unit firmware ver. 2.00 or later.

Utilization of Vehicle-installed Network Definition Files (CAN DBC, LIN LDF)

Data to be acquired using a bus monitor module (720240 or 720241) can be specified not only in digital code (hexadecimal or numeric), but also loaded from a network definition file (CAN DBC or LIN LDF).

Example of comparison and verification of a measured signal and CAN bus signal
You can trend the physical value of CAN bus data and the corresponding measured waveforms on the same screen at once. For example, an ignition switch ON/OFF signal, a CAN signal corresponding to that command, and an actual signal measured by a pressure sensor, etc. can be displayed and checked on the same screen, to verify the correlation of those signals.




Support for both AC and DC power (/DC option, DL850V only)

  • Low power consumption of 60 - 120 VA (typ.)
  • Low noise

The DL850V Vehicle Edition can be driven by a 12 V DC battery, vehicle’s cigarette lighter, or ordinary AC power. (We provide accessories for DC driving; see the list of accessories at the end of the catalog.)

"We thoroughly tested the ScopeCorders after the demonstration by Yokogawa and determined that the device met all our requirements perfectly"

Frank Schlieper - Senior German Sales Manager Power Controllers

"A big advantage is the plug-in modules, which are isolated and are suitable for input voltages up to 850 V. We need many channels, and we need to measure the net voltage directly. Since testing the controllers is a relatively slow process, we need long integration times: a feature which is supported by very few instruments."

Lars Alsdorf - Development Engineer

Berliner Verkehrsbetriebe, (BVG) - Frank Schumann

"The DL850 ScopeCorder from Yokogawa is ideal for us because it offers both analog and digital channels in sufficient numbers in one instrument. In addition, the device has a high withstand voltage up to 1,000 volts" "With the DL850 ScopeCorder we record the signals during a test drive and then take the time to evaluate them afterwards. For sporadic errors we regularly make long-term measurements in the workshop in which the loads are simulated by resistors"

Harmoniser – Natan Gothelf

"What we needed was an instrument combining multi-channel capability with high measurement accuracy, high sample rate and time resolution along with good display quality and the ability to zoom in on the fine detail of measured waveforms. After evaluating the available products on the market, we decided that the Yokogawa DL850 ScopeCorder was the one that best met our requirements."

My company has used Yokogawa ScopeCorder for about 15 years starting with the 708 model. My department has pretty much standardized on Yokogawa which allows multiple groups to use and borrow them as needed.

TT Engineered Solutions, Tim Taubert

The Yokogawa group have always taken good care of my equipment and instrumentation needs. I have been using the DL750 on some projects and all involved have asked how I am getting such amazing data and good measurements. I always use that opportunity to say it is not me, it is the equipment I use.

Yamaha Motor Co., Ltd.

We develop engines for racing motorcycles. Mainly, I'm in charge of developing measuring systems for engine performance evaluations and reliability tests.We do a variety of different evaluations on the engine test bench. We perform measurements on a regular basis of quite a number of items including the number of engine revolutions, torque, throttle opening, air-to-fuel ratio (A/F) which indicates the condition of the engine, concentrations of exhaust gases, pressure, and temperatures related to the exhaust and engine. We capture all of these signals and perform analysis using the DL750 ScopeCorder and the modular WE7000 PC-Based Measurement Instrument. Our job requires capturing suddenly-occurring abnormal phenomena as the engine turns and then observing the details while at the same time making long-duration observations of slow signals such as the air-to-fuel ratio (A/F). We use the DL750 ScopeCorder for such monitoring applications and measurement of valve behavior during unit testing.The DL750 has a color display which makes it easy to view 16 channels of data at once, and the long memory and zoom functions allow us to observe abnormal phenomena in detail.We also use the snapshot function frequently. It helps us tremendously by letting us freeze a waveform being displayed on screen and save it to MO disk or PC card. The DL750 also has an abundant array of interfaces so it's easy to use, and one reason we chose the DL750 is because of the Ethernet function that allows us to connect it to a network. We've been using DL series digital oscilloscopes for awhile, and we are very satisfied with them because they are easy to use and offer high cost-performance.

I work on development for hybrid vehicles. Especially in recent years, I've been involved with the Advanced Clean Energy Vehicle Project (ACE project) at NEDO (New Energy and Industrial Technology Development Organization).


The objective of the ACE (Advanced Clean Energy Vehicle) project for 2003 is to work in cooperation with all the automobile manufacturers in order to reduce carbon dioxide emissions by developing new vehicles that combine hybrid structure, greatly decreased fuel consumption, clean energy, and after treatment technology for exhaust gases.


At Hino Motors, our goal this year is to come out with a hybrid bus with two times the fuel efficiency compared with our previous heavy duty diesel busses. We brought in five of the DL750 ScopeCorders for development on this new hybrid bus.


The bus under development has a new hybrid system and electrical storage units, and we use the DL750s to capture various signals in that system. For the storage unit we capture cell voltage, module voltage, current, temperature and other signals. In the engine we look at RPM, torque, and controller output signals, and in the hybrid system we measure motor, controller, temperature and many other kinds of signals, all of which undergo subsequent analysis.


Before, when the project was focused on storage research, we used 10 of the DL716 ScopeCorders to measure voltage. The DL716 accepted 16 channels of isolated input, and the long memory of that oscilloscope gave us high resolution that was really convenient for us. We chose the DL750 this time because it carries over the features of the DL716, but has improved long memory, is smaller in size, and adds GP-IB and Ethernet support which we think will be useful in the future.


By hooking up the five DL750s to a notebook PC via GP-IB, we can gather all 80 channels worth of data together using our customized LabVIEW software. We can send measurement commands to the DL750 from the PC, and that really speeds up our work. By gathering various kinds of data measured from the actual vehicle, the DL750 helps us understand what's going on inside the hybrid systems as they operate. During development of the new hybrid bus we analyze everything from the measured RPMs at a given accelerator position to the voltage values in the storage unit to energy consumption, and this lets us determine the most fuel-efficient control conditions for the hybrid system.

The DL750 is fabulous. We have been using the unit to monitor AC line, investigate Instantaneous Stop conditions and to test live boards. It is safe and easy to operate (if you read the manual or receive technical service assistance). I truly recommend the unit to anyone that is involved in some kind of signal monitoring activity...it is great! I have only used 40% of its capacity more or less, but I am looking forward to squeeze every dollar we invested on it. I rate the unit at # 4 level because I am not familiar with other oscilloscopes similar to the DL750. Thanks.

Ford Motor Company, Essex, UK - Alasdair Gillespie

In the development of new engine control strategies we often have the need to capture and analyse many complex signals. To this end we have several Yokogawa Oscilloscopes including the DL750. The DL750 is an essential tool in our work, being used by engineers for a multitude of tasks: Software design and validation as well as Control system design and calibration.

In a recent case, we had a development issue with the control system for an engine actuator. On analysis of the signals within the software calibration tool we were unable to diagnose the issue. It wasn't until we used the DL750 with its high speed signal acquisition and multiple channel capability that we could fully understand what was going on.

In engineering, it is the understanding of a system's behavior that is the key to developing solutions. The DL750 gives us a window into the complexity of the signals in our systems. From there we have the means to develop highly refined control systems for our range of class leading diesel engines.

This is a powerful troubleshooting tool. It took me a couple of days to figure it out, but it really is versatile and capable of monitoring signals from instrument level all the way up to 480VAC. We have already used it to monitor & trend motor currents & frequency on our new production line. We were having troubles with the motor drive tripping, and we found out that the design speed/frequency for the application was estimated wrong from the beginning. We adjusted base frequencies for the product and it is running good now.


I have used similar laptop based equipment in the past, which had lots of interface parts & was not very reliable. This thing has everything rolled into one box, and is much more reliable and versatile.

American Electric Power, John Mandeville

We have 2 DL750s. They are easy to setup and use. The channel to channel isolation / cross is one the best unit I have found. There are 2 things that could have been done better. First there is no tilt stand on the bottom. Also, the developers view this as an enhanced scope. So the vertical and horizotal units are always in per division. This is a little bit confusing since I really would like to set the range and not the volt/div * 8 div. Otherwise this is a very nice instrument.
