Chapter 2 Command Systems
Programming Guide for DSA1000A series 2-42
Explanations The command transmits the data from the latest measurement to
the ouput buffer.
Return Value Such as 50000
13. :FETCh:HARMonics:AMPLitude:ALL?
Syntax :FETCh:HARMonics:AMPLitude:ALL?
Function The query returns the amplitude value of the first ten harmonics at
comma intervals and in the same unit of the current amplitude.
Explanations

If there are less than ten harmonics to measrure, the query
returns nothing for those unmeasured harmonics.

The unit of the returned value is the same as the unit of Y-axis.

The command transmits the data from the latest measurement
to the ouput buffer.
Return Value Such as
-1.01,-6.01,-7.01,-7.01,
-7.01,-7.01,-7.01, -7.01,
-7.01,-7.01
14. :FETCh:HARMonics:AMPLitude? <n>
Syntax :FETCh:HARMonics:AMPLitude? <n>
Function The query returns the specified harmonic amplitude, such as
:FETC:HARM:AMPL? 1
Explanations

<n> is an integer wthin 1 and 10.

The unit of the returned value is the same as the unit of Y-axis.

The query returns “---” if the harmonic to be read has no data.

The command transmits the data from the latest measurement
to the ouput buffer.
Return Value Such as -1.01
15. :FETCh:HARMonics[:DISTortion]?
Syntax :FETCh:HARMonics[:DISTortion]?
Function The query returns the percentage of THD (total harmonic
distortion).
Explanations The command transmits the data from the latest measurement to
the ouput buffer.
Return Value Such as 2.02
