Reset Performance at Transient Drop of Voltage
Detect the reset performance of the DUT at different Voltage drops. Applicable
for devices with reset function (for example, device installed with one or several
micro controllers) .
After turning on [On/Off] and triggering the waveform output, the instrument will
apply test pulse and detect the reset performance of the DUT, as shown in the
figure below.
The supply voltage drops from U
then rise to U
0.9U
0V by 5% and raise the voltage to U
10ms and 1s.

Start-up Characteristics
Detect DUT characteristics before and after vehicle startup.
After turning on [On/Off] and triggering the waveform output, the instrument will
apply the startup characteristic parameters as shown in the figure and table be-
low to related input terminals of the DUT simultaneously.
