DC Power Voltage Fluctuation Simulator

SG-7040  ( ISO 16750 )



SG-7040
SG-7040

SG-7040 simulator to reproduce power supply voltage fl uctuation to electronics devices in a vehicle and evaluate the immune resistibility against the fl uctuation. Max. 4 channels not only +B connection but also ACC, IG (and IG2), etc. can be synchronized for the reproduction.

 

- Features -

● ISO 16750 Standard compliant test (Possible to respond to private standards of the manufacturers).
● High resolution and high accuracy for the waveforms output realized with waveforms operation circuits built in the each channel.
● Easy and precise reproduction of the fl uctuation phenomena not only in the Standard but also arbitrarily enabled with the software control (USB).
● Insures less than 1μs for the synchronizing variation among the channels.
● Enables to put out the waveform data (CSV) which is measured with an oscilloscope in a real vehicle.
● Automated testing operation can be customized for reducing the man-hour.

Specification


The system is primarily comprised of the following three elements: multisequential oscillator, bipolar power source(s), and arbitrary waveform creation software. Appropriate bipolar power sources shall be selected and the multi-sequential oscillator shall be confi gured according to test requirements.

1. Multi-sequential Oscillator

・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.
