:READ:HARMonics:FREQuency:ALL?
Syntax
:READ:HARMonics:FREQuency:ALL?
Description
Executes one harmonic distortion measurement and returns the frequencies of the first 10 harmonics.
Remarks
If the number of harmonics under measurement is less than 10, the harmonics that are not measured do
not have return values.
This command will select data from the latest measurement results, and then transmit the data to the
output buffer.
This command is only available for GPSA mode.
Return Format
The query returns the frequencies in scientific notation (separated by commas). The unit is Hz.
For example, 4.550000000e+07,9.100000000e+07,1.365000000e+07
