16. :FETCh:HARMonics:FREQuency:ALL?
Syntax :FETCh:HARMonics:FREQuency:ALL?
Function The query returns the frequency of 10 harmonics at comma
intervals in Hz. The first harmonic is the fundamental wave.
Explanations

The command returns “0” for those unmeasured harmonics if
less than 10 harmonics to measrure.

The command transmits the data from the latest measurement
to the ouput buffer.
Return Value Such as 45500000,91000000,136500000,182000000, 227500000,
273000000,318500000,364000000,409500000,455000000
17. :FETCh:HARMonics:FREQuency? <n>
Syntax :FETCh:HARMonics:FREQuency? <n>
Function Queries the frequency of specified harmonic in Hz, such
as :FETC:HARM:FREQ? 1
Explanations

<n> is an integer wthin 1 and 10.

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 45500000
18. :FETCh:HARMonics:FUNDamental?
Syntax :FETCh:HARMonics:FUNDamental?
Function The query returns the fundamental wave freuqncy in Hz.
Explanations

The commands is the same
as :FETCh:HARMonics:FREQuency? 1

The command transmits the data from the latest measurement
to the ouput buffer.
Return Value Such as 45500000
19. :FETCh:OBWidth?
Syntax :FETCh:OBWidth?
Function The query returns 2 values at comma intervals: Occupied
BandWidth (Hz) and Transmit Freq Error (Hz).
Explanations The command transmits the data from the latest measurement to
the ouput buffer.
Return Value Such as 1860000,40000
