Ocp&Opp - Chroma 63200A Series Operation & Programming Manual

Operation Overview
current bias (I_DC), the loading sine wave (I_AC) and sine wave frequency (Frequency).
The lowest point of sine wave cannot be smaller than 0 ampere. As Figure 3-9 shows Ch1 is
the actual loading current waveform and Ch2 is the voltage waveform of the UUT (AC
component.)
ADVA
To enter into SWD mode, press and select SWD and then press Enter.
Parameters:
I_DC: Set the DC loading current bias.
I_AC: Set the AC peak to peak loading sine wave.
FREQ: Set the sine wave frequency 0~20KHz.

3.7.3 OCP&OPP
The OCP (or OPP) provides ramped up current (or power) for the Load to test the UUT
voltage whether has reached trigger voltage level and to judge if the protection is acting
normally or not.
