VOLT 2 Sets the voltage setpoint to 2 V
CV:CURR:LIM 20A Sets the current limit value to 20 A in CV mode
INPUT ON Turns on the load
4.14.5 Current Rise/Fall Rate in CC Mode
Example: Set the load to CCH mode, set the current value to 2 A; set the current rise rate (Curr Rise Rate) in CC mode to 0.002 A/μs;
set the current fall rate (Curr Fall Rate) in CC mode to 0.005 A/μs; turn on the load; turn off the load.
The detailed operations are shown below:
For the above operating procedures, the corresponding SCPI commands should be:
MODE CCH Sets the mode
CURR 2 Sets the current value to 2 A
CURR:RISE:RATE 0.002 Sets the current rise rate in CC mode to 0.002 A/μs
CURR:FALL:RATE 0.005 Sets the current fall rate in CC mode to 0.005 A/μs
INPUT ON Turns on the load
