:READ:HARMonics[:DISTortion]? 
Syntax
:READ:HARMonics[:DISTortion]? 
Description
Executes one harmonic distortion measurement and returns the percentage of the total harmonic 
distortion. 
Remarks
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
Queries the percentage of the total harmonic distortion in scientific notation. For example, 
2.490393000e+02 
: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
