Power Supply Function
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

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.
• t: Time time (in ms) t1: 5ms
• U: Voltage (in V) t2: 15ms
• U
s
: 18V t3: 50ms
• U
A
: 21V t4: 10000ms
• U
T
: 42V t5: 100ms
