Source[<N>]]:Fm:internal:frequency - Rigol DG800 Pro Series Programming Manual

Command System
Name
<lim_set>
<lim_query>
Remarks
• Frequency deviation represents the peak variation in frequency of the
modulated waveform from the carrier frequency. The minimum frequency
deviation is 0 Hz and the maximum value is limited by the frequency setting
value (
-
-
• When an external modulation source (
the frequency deviation is controlled by the signal from the real-panel [AUX
IN/OUT] connector.
• When [:SOURce[<n>]] or [<n>] is omitted, it is interpreted as CH1.
Return Format
The query returns the frequency deviation in scientific notation. For example, the
query might return +1.000000000000000E+02, indicating that the frequency
deviation is 100 Hz.
Examples
:SOURce1:FM:DEViation 100 /*Sets the FM frequency deviation to 100
Hz for CH1.*/
:SOURce1:FM:DEViation? /*Queries the FM frequency deviation for
CH1. The query returns +1.000000000000000E+02.*/
