:READ:HARMonics:AMPLitude:ALL?
Syntax
:READ:HARMonics:AMPLitude:ALL?
Description
Execute a harmonic distortion measurement and return the amplitudes of the first 10 harmonics.
Explanation
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 values is the same with the current Y-axis unit.
This command will select data from the latest measurement results and transmit the data to the output
buffer.
Return Format
The query returns the amplitudes of the first 10 harmonics in scientific notation (separated by commas).
For example,
-1.692102E+01,-6.458423E+01,-7.509421E+01,-7.924328E+01,-7.847027E+01,-7.885457E+01,-7.8823
58E+01, -7.921457E+01,-7.923057E+01,-7.915358E+01.
:READ:HARMonics:AMPLitude? <n>
Syntax
:READ:HARMonics:AMPLitude? <n>
Description
Execute a harmonic distortion measurement and return the amplitude of the specified harmonic.
Parameter
Explanation
The amplitude unit of the return value is the same 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 transmit the data to the output
buffer.
Return Format
The query returns the amplitude of the specified harmonic in scientific notation. For example,
-1.692102E+01.
