:READ:HARMonics:AMPLitude:ALL?
Syntax
:READ:HARMonics:AMPLitude:ALL?
Description
Executes one harmonic distortion measurement and returns the amplitudes 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.
The amplitude unit of the return value is consistent with the current Y-axis unit.
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 amplitudes of the first 10 harmonics in scientific notation. They are separated by
commas.
For example,
-1.692102000e+01,-6.458423000e+01,-7.509421000e+01,-7.924328000e+01,-7.847027000e+01,-7.885
457000e+01,-7.882358000e+01, -7.921457000e+01,-7.923057000e+01,-7.915358000e+01

Remarks
The amplitude unit of the return value is consistent with the current Y-axis unit.
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.
This command is only available for GPSA mode.
Return Format
The query returns the amplitude of the specified harmonic in scientific notation.
For example, -1.692102000e+01
