Pulse mode
Under pulse mode, after enabling dynamic test operation, the load will switch to
B value after receipt of a trigger signal and switch back to A value after
maintaining B for pulse width time.
Taking CC mode as example (operations under other modes are similar), when
output voltage and current of the tested instrument are 10 V and 3 A
respectively, the load current will switch from 1 A and 2 A. Set the dynamic test
parameters and perform the test as follows:
