4.7.3 ISO21848
A test wave completely conforming to International Standard ISO21848 is built
inside the device, which can be used for the test of Electrical and electronic
equipment for a supply voltage of 42V - Electrical loads. The user can directly
and quickly recall this function during test.
U test pulse
max,dyn
Detect the function when the DUT is under maximum dynamic Voltage U
and simulate the maximum dynamic Voltage of high-energy pulse raised from
throw load in 42V electrical system, where the upper limit is the protection
voltage of throw load.
Apply 1 test pulse to the DUT, as shown below:

t: time (in ms)

U: Voltage (in V)
Supply Voltage Transient Drop (Momentary-Drop)
Simulate the affect from short circuit when fuse element of another circuit is melt.
Detect the function status of the DUT at transient drop of Voltage.
