Mod/Trig/FSK] connector. Positive signal level corresponds to frequency increase, and negative
signal level corresponds to frequency decrease. Lower signal levels produce less deviation. For
example, if the frequency deviation is set to 1 kHz, +5 V signal level corresponds to a 1 kHz increase in
frequency and -5 V signal level corresponds to a 1 kHz decrease in frequency.
Return Format
The query returns the frequency deviation in scientific notation, with 7 effective digits. For example,
1.02 (the frequency deviation is 100 Hz).
Example
:SOUR1:FM 100 /*Sets the FM frequency deviation of CH1 to 100 Hz.*/
:SOUR1:FM? /*Queries the FM frequency deviation of CH1 and the query returns 1.02.*/
[:SOURce[<n>]][:MOD]:FM:INTernal:FREQuency
Syntax
[:SOURce[<n>]][:MOD]:FM:INTernal:FREQuency {<frequency>|MINimum|MAXimum}
[:SOURce[<n>]][:MOD]:FM:INTernal:FREQuency? [MINimum|MAXimum]
Description
Sets the FM modulation frequency of the specified channel.
Queries the FM modulation frequency of the specified channel.
Parameter
Name Type Range Default
[<n>] Discrete 1|2 1
<frequency> Real 2 mHz to 1 MHz 100 Hz
Remarks

This command is only applicable to the internal modulation source
( [:SOURce[<n>]][:MOD]:FM:SOURce ).

When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
Return Format
The query returns the FM modulation frequency in scientific notation, with 7 effective digits. For example,
1.02 (the FM modulation frequency is 150 Hz).
Example
:SOUR1:FM:INT:FREQ 150 /*Sets the FM modulation frequency of CH1 to 150 Hz.*/
:SOUR1:FM:INT:FREQ? /*Queries the FM modulation frequency of CH1 and the query returns
1.02.*/
