  The system is primarily comprised of the following three elements: multi-channel signal generator, bipolar power
  source(s), and arbitrary waveform creation software.
  Appropriate bipolar power sources shall be selected and the multi-channel signal generator shall be configured
  according to test requirements.

  1. Multi-channel signal generator

  ・Modular construction for a maximum of four channels ・Arbitrary waveform creation (DC, ramp wave, sine wave, exponential wave, frequency modulation, amplitude modulation) ・Waveform sequence creation

  2. Arbitrary Waveform Creation Software

  The arbitrary waveform creation software easily creates complicated waveforms with repeated voltage and time ramping with its superb GUI.

  3. Bipolar Power Source

  High-speed bipolar power source is selected according to the DUT power rating.

  In multichannel tests it is important to ensure each individual channel is precisely synchronized. This system guarantees a synchronization delay of 1μs or less by compensating for output timing differences from the power amplifiers being connected, whereas other systems are not equipped with similar capability, which often leads to a erroneous test.

  

• CSV Waveform EXCEL Operation Example

  Imports non-standard test waveforms such as waveforms data collected in vehicle environments as CSV files, and generates these waveforms from the signal generator. Not available thus far with existing conventional equipment due to the limited memory capacity , the SG-7040A with 512 k words memory is a perfect solution to accurately perform complex voltage variations, fluctuations, dips and dropouts.

  

• Automated Simulations

  ■ Example 1: CAN Communication Control
  CAN is one of the most widely adopted system bus in automotive technology. Automated testing can be done by reading CAN communication protocols into the software and defining malfunction of the DUT.
  

  ■ Example 2: “Dark Current” Measurement
  Some automobile manufacturers implement “Dark Current” measurements. This system allows dark current measurements in conjunction with voltage fluctuation simulations.
  

  ■ Example 3: Check Device
  Automated testing by incorporating Pass/Fail judgment circuit with received signals from the DUT such as voltage, current, and frequency.
