High Power Electronic Load 63200A Series Operation & Programming Manual
3-26
Parameters:
TYPE: Set the OCP(0) &OPP (1) modes.
TRG: Set the trigger voltage. When the UUT output voltage is lower than the trigger level,
the Load will stop loading current.
STR_I: Set the current start level.
EDN_I: Set the current end level.
STEP: Set the current change steps. The range is 1 to 1,000
.
DWELL: Set the dwell time. The dwell time is the time from start to end of a set current
level. The set range is
10μs to 1,000ms.
SPECH/L: Set the OCP spec to LOW or HIGH level.
SWP (CC Dynamic Sweep) 3.7.4
In SWP mode, the Load provides a unique constant current dynamic sweep to use
frequency conversion to find out the UUT voltage of worst case.
The CC dynamic sweep allows the user to program two load levels (Load1 and Load2), start
frequency, end frequency, step frequency, dwell, duty and slew rate (rise & fall). During
operation, the loading will switch between two load levels according to the specified value.

To enter into SWP mode, press and select SWP and then press Enter.
Parameters:
I_MAX: Set the maximum current level.
I_MIN: Set the minimum current level.
FSTER: Set the start frequency. The range is 0.01Hz to 50kHz.
FEND: Set the end frequency. The range is 0.01Hz to 50kHz.
FSTEP: Set the step frequency. The range is 0.01Hz to 50kHz.
DWELL: Set the dwell time. The dwell time is the time from start to end of a set step
frequency. The set range is 1ms to 100s.
DUTY: Set the duty of load. The duty can set to 1%-99% but will be limited to the transient
time between two load levels.
