Power Supply Function
• t: Time (in ms)
• U: Voltage (in V)
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
low
to 0.95U
low
by 5% and keeps for 5s, and
then rise to U
low
and keep for at least 10s for function test. Then, drop Voltage to
0.9U
low
, and so on. As shown in the figure below, drop the voltage from U
low
to
0V by 5% and raise the voltage to U
low
. The Rise and Fall time shall be between
10ms and 1s.
• t: Time (in s)
• Y: U
low

Start-up Characteristics
Detect DUT characteristics before and after vehicle startup.
