:FETCh:HARMonics:FREQuency:ALL?
Syntax
:FETCh:HARMonics:FREQuency:ALL?
Description
Queries the frequencies of the first 10 harmonics. The first harmonic is the fundamental waveform.
Remarks
This command is only valid when the harmonic distortion measurement in GPSA mode is enabled.
This command will select data from the latest measurement results, and then transmit the data to the
output buffer.
Return Format
The query returns the frequencies of the first 10 harmonics in scientific notation (separated by commas).
The unit is Hz.
If the number of harmonics under measurement is less than 10, the harmonics that are not measured do
not have return values.
Example
The following query returns
4.550000000e+07,9.100000000e+07,1.365000000e+08,1.820000000e+08,2.275000000e+08,2.7300000
00e+08,3.185000000e+08,3.640000000e+08,4.095000000e+08,4.550000000e+08.

Remarks
This command is only valid when the harmonic distortion measurement in GPSA mode is enabled.
The query returns --- when the harmonic read does not have data.
This command will select data from the latest measurement results, and then transmit the data to the
output buffer.
Return Format
The query returns the frequency of the specified harmonic in scientific notation. The unit is Hz.
Example
The following query returns 4.550000000e+07.
