:FETCh:HARMonics:FREQuency? <n>
Syntax
:FETCh:HARMonics:FREQuency? <n>
Description
Query the frequency of the specified harmonic.
Parameter
Name
Type Range Default
<n> Integer 1 to 10 --
Explanation
This command is only available when the harmonic distortion measurement is enabled.
The query returns --- when the harmonic read does not have data.
This command will select data from the latest measurement results and transmit the data to the output
buffer.
Return Format
The query returns the frequency of the specified harmonic in integer and the unit is Hz.
Example
The query below returns 45500000.
:FETCh:HARMonics:FREQuency? 1
:FETCh:HARMonics:FUNDamental?
Syntax
:FETCh:HARMonics:FUNDamental?
Description
Query the frequency of the fundamental waveform.
Explanation
This command is only available when the harmonic distortion measurement is enabled.
This command is equivalent to the :FETCh:HARMonics:FREQuency? 1 command.
This command will select data from the latest measurement results and transmit the data to the output
buffer.
Return Format
The query returns the frequency of the fundamental waveform in integer and the unit is Hz.
Example
The query below returns 45500000.
