DualCapture: A Powerful Tool for Durability Test Data Analysis
Simultaneous High-Speed and Low-Speed Recording Using DualCapture
During durability testing, it is necessary to monitor the long-term trends of your data as well as capture the high speed transients that might occur. This presents a challenge as trend data is usually recorded at a slower sampling speed that might miss the transient phenomena. To meet this challenge, the DL750 offers the DualCapture function.DualCapture
Using DualCapture, you can now record your trend data with a slow sampling speed and still be able to capture the transient phenomena with a faster sampling speed.
- Integration of a High-Speed sampler (Oscilloscope) and Low-Speed sampler (Recorder) in a Single Unit
High-speed sampler: Trigger on abnormal high-speed phenomena
Low-speed in a sampler: Roll recording (trend recording)
- Separate Memory Management for Each sampler
Maximum memory for low-speed: 100 MW
Maximum memory for high-speed: 10 kW * 100 screens - High-Speed Sampling Triggered Only by Abnormal Events Occurring during Long-Term Observation (Low-Speed Sampling)
Effective for separately capturing data at high speed
- Long Memory Equivalent to 1 Teraword (1012)
To acquire many hours of data at the higher sampling rate (10 MS/s) would require Teraword of memory:
(8 hr to 24 hr) × 60 min × 60 sec × 10 MS/s × 16 channels = 4.6 to 138 TW
| The waveform shown above was captured at a sampling rate of 50 kS/s. The occurrence of noise can be confirmed in the graph, but the time resolution is too low to capture the waveform accurately. | With DualCapture, the user sets triggers for capturing sudden phenomena. Up to 100 phenomena can be collected in a memory length of 10 kW at a maximum sampling rate of 10 MS/s. |

This function downloads values of waveform parameters periodically, activates MS Excel automatically, and graphs the calculated values on the PC. This enables you to check the parameter trends at a glance.
DC12 V Power Supply
* AC and DC power supplies can be used together to ensure a highly reliable power source. An extemal DC source such as a car battery is used for the DC power supply.
For AC and DC Input
Adding this option enables the DL750 to be run under DC power (10-18 V) as well as AC power (100-120 V/200-240 V). This allows the instrument to be used not only for in-vehicle measurements, but also in a wide range of other testing locations. The power source is switched automatically (when AC and DC are used simultaneously, AC is given priority).
Thin ProfileThe DC Power Box is only 20 millimeters wide1, and weighs 800 grams.

A Power Supply Backup System for Long Duration Observations
Simultaneous input of AC and DC power prevents loss of data when making observations over long periods of time (requires an external DC source such as a car battery). The DC input can be used as a backup power supply. If the AC power goes down, the DL instantly switches to DC input without interrupting the measurement.

 Multi-Channel 2-Location Zoom Function |
A Wide Range of Trigger
Having a wide range of triggers is of course very useful for obtaining stable observations of variety of different waveforms. In addition, the GUI menu makes setting trigger conditions easy and intuitive.
Wave Window Trigger
Automatically Triggers on Abnormalities in Power Supply WaveformsThis function comes standard with the DL750 to allow observation power supply waveforms. In addition to traditional power supply troubles such as sudden outages, sags, and surges, you can make efficient real time observations of frequency fluctuations and voltage drops. The trigger activates when a signal exceeds the allowable values determined by comparing a defined waveform (wave window) with an actual waveform in real time. Comparative waveforms can be automatically produced in real time based on measured waveforms. Detection on all 16 analog channels is available (with OR conditions).
Action-on Trigger
Automatically Save Measured Data
When this trigger is activated, the DL750 performs a specified action each time a waveform is captured and a screen is displayed. This feature is useful for automatically and reliably saving data (e.g., for data collection in automated, continuous tests).
Manual TriggerIn Addition to Simple and Enhanced Triggers, a Trigger Can be Activated Manually with the Press of a Button
With this feature, a trigger can be executed whenever you like, separate from the preset trigger conditions.
History Memory and Smart Search
Enables You to Access Large Amounts of Captured Data
History Memory and History Search (Zone Search) 
Occasionally, you may capture an abnormal waveform and then have it quickly disappear from the display as new data is acquired. It is not always possible to manually Start and Stop data acquisition to catch the abnormal waveform and have it displayed.
The History Memory function was designed for such situations. It divides long memory into a number of blocks and automatically stores up to 2000 previously captured waveforms. This means you can reliably save displayed waveforms to memory even when there are events for which trigger conditions cannot be set.
| The Zone Search function lets you define zones on the screen and find all previously captured waveforms that either pass or don't pass through the user-defined zone. Up to four zones can be defined. |  |
| Search (Edge Search) and Zoom The Edge Search counts rising and falling edges in the captured data. It automatically searches for the desired edges and displayed them on a zoom screen. |
 |
DSP Channel Real-Time Calculation Function (with the /G3 Option)
- Real-time display of calculated waveforms in roll mode
- Triggers on calculated waveforms
- Calculated parameters such as cutoff of digital filtering and frequency can be changed in real time
- Simultaneously displays up to 16 analog CH + 6 DSP CH
- Provides the same memory length as with analog channels
- Arithmetical calculation between channels (addition, subtraction, multiplication, division), digital filtering (LPF, BFP, HPF), differentiation, and integration
Automatically Measure Waveform Parameters
Easily Find and Display Waveform Frequency, Rise Time, and ParametersWaveform parameterssuch as voltage, frequency, and RMS are measured automatically.
In addition to general parameter measurement functions, the DL750 comes standard with functions such as the following:
| Cycle Statistical Calculation This function calculates statistical information about the waveform. Maximum value, minimum value, average value, and standard deviations are calculated automatically for each waveform parameter. In addition, you can instantaneously search for the cycle containing the maximum value and display it on the zoom screen. This cycle statistical calculation greatly improves your insight enabling you to analyze transient phenomena captured using the long recording memory |
 |
| Pulse Count This function automatically calculates and displays the pulse count for an input signal in a range defined by cursors. It is useful for measuring rotation pulse counts for equipment like stepping motors, for tracking error signal counts for optical discs and other devices, and for counting encoder output pulse counts. |
Single-Cycle Mode In this mode, the DL750 determines a cycle, then calculates items pertaining to the voltage axis and surface area in that cycle. Range settings can be used to obtain accurate single-cycle RMS and average value measurements. |
 |
|
Linear Scaling
Convert Measured Voltage Values into Physical Values for Direct Reading| This function automatically performs the following calculation based on a scaling coefficient A and offset B: Y = AX + B (X is a measured value and Y is the scale value). The results of this calculation are displayed in cursor measurement values and waveform parameter measurement values. In addition, a user-determined scale value can be defined for any two measurement points, P1 and P2. |
 |
GO/NO-GO Judgment
Automatic Waveform Determinations| With this function, the user specifies a zone or waveform parameter for a measured waveform. The measurement signal is evaluated and a specified action is performed automatically based on the determination. Available actions include outputting a screenshot to a specified destination, saving waveform data to a specified storage medium, sounding a buzzer, and sending email. |  |
User-Defined Math Functions (Optional)
Perform Complex Calculations| The DL750 comes standard with basic arithmetic operations (addition, subtraction, multiplication, division), FFT (power spectrum), and phase shifting (calculating a phase shift between channels). For more flexible and complex calculations, an optional user-defined math function package is available. With this option, you can define as many as 8 different formulas using a wide range of functions, including a triangle function, differentiation, integration, square root, digital filter, and seven different FFT functions. You can also specify the results of a calculation as a parameter in another formula. With these capabilities, the DL750 makes it easy to perform complex calculations that, in the past, could only have been done by loading data onto a PC. |
 |
Display and Data Recording Functions
Recorder-Like Real-Time Recording for Long Periods| With the optional internal hard drive, you can record measurements to the hard drive in real time. This makes it easier to manage and analyze data using PCs and other tools. Maximum data capacity: 1 GW Maximum sampling rate: 100 kS/s (using 1 channel only) |
 |
Memory Backup Function
| Protect Your Data Even If the Power Supply Goes Out This function backs up about 10 minutes of data saved to the acquisition memory immediately prior to power loss. Memory backup helps you avoid losing important data even if the power supply is unstable and gets cut off. (Backup time varies according to the usage environment. Four AA batteries are required for memory backup.) |
 |
Snapshot Function
Enables On-Screen Waveform Comparisons  Using the snapshot function, you can freeze the currently displayed waveform with the touch of a button. Snapshots are useful for comparing a reference waveform with an input waveform. In addition, snapshots can be saved to and loaded from storage media. |
 |
X-Y Display Function
Display an Overlay of up to Four X-Y Displays  This function lets you display multiple X-Y plots together, making relative phase comparisons easy. The X-Y display function is a powerful tool for applications such as evaluating DC motors based on a Lissajous waveform. |
 |
All-Channel Menu
Quickly View the Setup of All Channels  This menu lets you review and modify all of the channel setups from a single screen display. Parameters such as voltage axis sensitivity, screen scale settings, and linear scaling can be configured for each channel. |

Reviews
Detroit Energy, Mark
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.

I love this DL-750 scopecorder. The technicians here call it "my mistress". This is the single most powerful general purpose piece of test equipment I have ever seen. It found in one day a problem we lived with for 13 years, and paid for itself in one day. This machine excells at finding glitch events involving mixed signal types, such as relay logic, high and low voiltage AC and DC signals, AC or DC current signals, and 4-20 ma process controls. With 16 channels you can see a lot of data in one test. We also used this to investigate an electrical fire incident and found a very obscure design flaw, again in one day. We used the VGA output and a projector unit for a wall size view in a conf room and could step thru the circuit events a millisecond at a time, with 100% understanding of what was happening during a complex Y/Delta motor start sequence. This also found boiler trip problems where the event was so fast the flame safeguard computer was giving the wrong first out indication. The DL750 nailed the problem first time. I think this tool has gotten me two promotions in pay grade. It takes some time to learn, so don't expect to rent one and fix the world in two days. Buy it and learn it. Our DL750 was so useful and employed so much that the boss suggested I buy a second one. How often does that happen? Our second one, a DL750P named "The Terminator" is even better than the DL750.

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.

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.

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.
