Measurement Commands

MEASure[:SCALar]:FREQuency?

This command is used to read the current output frequency value.

Command syntax

MEASure[:SCALar]:FREQuency?

Returns

<NR2>

MEASure[:SCALar]:CURRent[:AC]:PEAK?

This command is used to read the current peak output current.

Command syntax

MEASure[:SCALar]:CURRent[:AC]:PEAK?

Returns

<NR2>

MEASure[:SCALar]:CURRent[:AC]:PEAK:MAXimum?

This command is used to read the current maximum peak current.

Command syntax

MEASure[:SCALar]:CURRent[:AC]:PEAK:MAXimum?

Returns

<NR2>

MEASure?

FETCh?

This command is used to read the measurement frequency, RMS voltage, RMS

current, active power measurement, power factor measurement, apparent

power measurement, peak current measurement, maximum peak current

measurement.

Parameters

None

Note: The FETCh and MEASure instructions also read various parameter values, except that

FETCh reads the last measured value and MEASure is the re-measured value. FETCh

speed faster, but the accuracy of MEASure higher.
