The SG-7040 Series simulates power supply voltage fluctuation to test automotive electronics. Connections of automotive electronics are not limited to +B, but connections are also done to ACC and IG.
In response to testing needs for synchronized, multi-channel fluctuation simulations, the SG-7040 Series can be configured with one to four sequential oscillators and with the relevant number of high speed bipolar power amplifiers to carry out highly accurate and fast response tests on multi-channel basis.
The SG-7040 system is primarily comprised of the following three components: multi-sequential oscillator, bipolar power amplifier and arbitrary waveform creation software. The required number of channels of multi-sequential oscillator shall be configured according to test requirements and appropriate bipolar power amplifiers shall be selected according to the current requirement for each line of the device under test.
1. Multi-sequential Oscillator SG-7040
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.
