Programmable AC/DC Electronic Load 63800 Series Operation & Programming Manual
Example : RES:LIM?

8.6.3.4 Voltage Subsystem

[LOAD:]
VOLTage
[:LEVel]
[:AMPLitude]
:DC
[LOAD:]VOLTage[:LEV][:AMPL]:DC
Description: This command sets the DC voltage of the electronic load. The electronic load
insures that the load voltage stays constant at the set value.
Setting Syntax : [LOAD:]VOLTage[:LEV][:AMPL]:DC
Setting Parameter : <NR2>, Range: 7.50 ~ 500.00, Unit: V
Query Syntax : [LOAD:]VOLTage[:LEV][:AMPL]:DC?
Response Parameter: <NR2>
Example : VOLT:DC 20

8.6.3.5 Crest Factor Subsystem

[LOAD:]
CFAC
[:LEVel]
[:AMPLitude]
[:AC]
:DC
:LIMit?
[LOAD:]CFAC[:LEV][:AMPL][:AC]
Description: This command sets the crest factor of the electronic load. The electronic load will
attempt to program the crest factor to a value as close as possible to the set value. The ability
to do so will be affected by the mode and the power factor setting.
Setting Syntax : [LOAD:]CFAC[:LEV][:AMPL][:AC]
Setting Parameter : <NR2>, Range: 1.414 ~ 5.000
Query Syntax : [LOAD:]CFAC[:LEV][:AMPL][:AC]?
Response Parameter: <NR2>
Example : CFAC 1.414
[LOAD:]CFAC[:LEV][:AMPL]:DC
Description: It sets the value CF, this command is only operating in DC Rectified Mode.
Setting Syntax : [LOAD:]CFAC[:LEV][:AMPL]:DC
Setting Parameter : <NR2>, Range: 1.414 ~ 5.000
Query Syntax : [LOAD:]CFAC[:LEV][:AMPL]:DC?
Response Parameter: <NR2>
Example : CFAC:DC 1.414
