Measurement Subsystem (Frequency) Commands
This subsystem programs the frequency measurement capability of the ac source.
Two measurement commands are available: MEASure and FETCh. MEASure
triggers the acquisition of new measurement data before returning a reading.
FETCh returns a reading computed from previously acquired data.
For Keysight 6811C/6812C/6813C Option 020 only, all standard ac source
MEASure or FETCh functions are available for the Main Output of the ac source as
well as the Power Analyzer input. The SENSe:NSELect command selects the
measurement source that will return data.
Subsystem syntax
MEASure:FREQuency?
FETCh:FREQuency?
This query returns the output frequency in hertz.
For Keysight 6811C/6812C/6813C Option 020 only, when the Power Analyzer
input is selected as the measurement source, this command returns the actual
frequency measured at the V SENSE input channel. When the Main Output of the
ac source is selected as the measurement source, this command returns the
programmed output frequency.
MEASure | FETCh
[:SCALar]
:FREQuency Returns the output frequency
NOTE
With no signal connected to the Power Analyzer input, this command may return
a very high frequency value. This is normal, since there is no external frequency
for the measurement circuit to detect.
Query syntax MEASure:[SCALar]:FREQuency?
FETCh:[SCALar]:FREQuency?
Parameters None
