RIGOL Chapter 2 Command System
2-58 DSA800 Programming Guide
:FETCh:HARMonics[:DISTortion]?
Syntax
:FETCh:HARMonics[:DISTortion]?
Description
Query the percentage of the total harmonic distortion.
Explanation
This command is only available when the harmonic distortion measurement is enabled.
This command will select data from the latest measurement results and transmit the data to the output
buffer.
Return Format
The query returns the percentage of the total harmonic distortion in scientific notation.
Example
The query below returns 2.490393E+02.
:FETCh:HARMonics:DISTortion?
:FETCh:HARMonics:FREQuency:ALL?
Syntax
:FETCh:HARMonics:FREQuency:ALL?
Description
Query the frequencies of the first 10 harmonics and the first harmonic is the fundamental waveform.
Explanation
This command is only available when the harmonic distortion measurement is enabled.
This command will select data from the latest measurement results and transmit the data to the output
buffer.
Return Format
The query returns the frequencies of the first 10 harmonics in integer (separated by commas) and the unit
is Hz.
If the number of harmonics under measurement is less than 10, the harmonics that are not measured do
not have return values.
Example
The query below returns
45500000,91000000,136500000,182000000,227500000,273000000,318500000,364000000,409500000,4
55000000.
