:FETCh:HARMonics:AMPLitude? <n>
Syntax
:FETCh:HARMonics:AMPLitude? <n>
Description
Queries the amplitude of the specified harmonic.
Parameter
Name
Type
Range
Default
<n>
Integer
1 to 10
——
Remarks
This command is only valid when the harmonic distortion measurement in GPSA mode is enabled.
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.
Return Format
The query returns the amplitude of the specified harmonic in scientific notation.
Example
The following query returns -1.692102000e+01.
:FETCh:HARMonics:AMPLitude? 1
:FETCh:HARMonics[:DISTortion]?
Syntax
:FETCh:HARMonics[:DISTortion]?
Description
Queries the percentage of the total harmonic distortion.
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 percentage of the total harmonic distortion in scientific notation.
Example
The following query returns 1.510000000e-02.
:FETCh:HARMonics:DISTortion?
