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.

Web Services

Turn Your DL750 into a Web Server

The DL750 can function as an independent Web server. Connect to your DL750 directly using Internet Explorer, and access a variety of services.

 

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.

DC12 V Power Supply

* 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

 

DC Power Box fits compactly on the rear panel (fits within the height of the feet of the DL1)	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

This option provides lower power consumption than when using an external DC/AC converter. This results in higher efficiency and significantly lower power consumption.

• Approximately 60 VA (typical value for 8 CH/10 MS/s)3
• Approximately 80 VA (typical value for 16 CH/10 MS/s)3

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.
