MEASure | FETCh
[:SCALar]
:CURRent
:AMPLitude
:MAX
:CREStfactor?
:PEAK
MEASure[:SCALar]:CURRent?
FETCh[:SCALar]:CURRent?
Description: Return the RMS / real time (AC Mode / DC Mode) current measured at the input
of electronic load.
Query Syntax : MEASure:CURRent?
Response Parameter: <NR2>
Example : MEAS:CURR?
MEASure[:SCALar]:CURRent:AMPLitude:HOLD
FETCh [:SCALar]:CURRent:AMPLitude:HOLD
Description: This command will define the peak current measurement mode. If the hold
command is set to ON, the peak current measurement is updated only when the value
measured exceed the last measured value. If the hold command is set to OFF, the peak
current measurement is updated each cycle. (AC mode only)
Setting Syntax : MEASure[:SCALar]:CURRent:AMPLitude:HOLD
Setting Parameter : 0 | OFF, 1 | ON
Query Syntax : MEASure[:SCALar]:CURRent:AMPLitude:HOLD?
Response Parameter: <NR1>
Example : MEAS:CURR:AMPL:HOLD ON
MEASure[:SCALar]:CURRent:AMPLitude:MAX?
FETCh[:SCALar]:CURRent:AMPLitude:MAX?
Description: Return the peak current measured at the input of electronic load.
Query Syntax : MEASure:CURRent:AMPLitude:MAX?
Response Parameter: <NR2>
Example : MEAS:CURR:AMPL:MAX?
MEASure[:SCALar]:CURRent:CREStfactor?
FETCh[:SCALar]:CURRent:CREStfactor?
Description: Return the current crest factor of the load. This is the ratio of peak load current to
RMS load current.
Query Syntax : MEASure:CURRent:CREStfactor?
Response Parameter: <NR2>
Return RMS / real time value of the current
(AC Mode / DC Mode)
:HOLD The highest peak current measurement is held
Return peak current
Return current crest factor
:NEGative? Return negative peak current
:POSitive? Return positive peak current
