
MEASure[:SCALar]:FREQuency?
This returns the external sync signal frequency in Hz units. The external sync signal frequency
measurement range is 38.0 Hz to 525.0 Hz. If the measured value exceeds the measurement range,
999.9 Hz is returned as a measurement error.
The frequency measurement can only be performed in external synchronization mode (AC-SYNC
or AC+DC-SYNC). ([3, “Invalid in this mode”] error occurs.)
Syntax: MEASure[:SCALar]:FREQuency?
Parameters: None
Query example: MEAS:FREQ?
Response format:
Response example: 50.4

MEASure[:SCALar]:POWer:AC:APParent?
This returns the apparent power in VA units. The apparent power measurement full scale is 1400
VA. If the measured value exceeds the measurement range, 9999 VA is returned as a measurement
error.
Syntax: MEASure[:SCALar]:POWer:AC:APParent?
Parameters: None
Query example: MEAS:POW:AC:APP?
Response format:
Response example: 367

MEASure[:SCALar]:POWer:AC:PFACtor?
This returns the output power factor. The power factor measurement range is 0.00 to 1.00. When
the measured value exceeds the measurement range, 9.99 is returned as a measurement error.
The power factor is calculated as “effective power/apparent power”.
Syntax: MEASure[:SCALar]:POWer:AC:PFACtor?
Parameters: None
Query example: MEAS:POW:AC:PFAC?
Response format:
Response example: 0.68
