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.
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. |
FTP
Easily copy and paste files to and from a PC from the internal flash memory drive and other internal storage media. You don't have to use a separate program to transfer the data.Data Capture
Download screen images periodically or manually. Download waveform data, start or stop a measurement, or setup a split display by using this menu.Measurement Trend
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.
* AC and DC power supplies can be used together to ensure a highly reliable power source. An external 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 Profile
The DC Power Box is only 20 millimeters wide1, and weighs 800 grams.
The Power Box fits compactly on the rear panel.2

The DL can still be placed on its back with the option installed. |
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.
Low Power Consumption
Low Emission Noise
Emission noise is greatly reduced compared with using an external DC/AC converter. High voltage switching noise is no longer a problem.

Multi-Channel 2-Location Zoom Function |
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.
Automatically Triggers on Abnormalities in Power Supply Waveforms
This 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).
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 Trigger
In 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.
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. |
Easily Find and Display Waveform Frequency, Rise Time, and Parameters
Waveform 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. |
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. |
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. |
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. |
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) |
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.) |
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. |
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. |
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. |
Increase the Viewing Area of the Display With the SVGA color TFT liquid crystal display, the number of display pixels has been greatly increased. For wide waveform display, set the resolution to 750 × 512 pixels. |
