:FM:DEViation

[SOURce]:FM:SENSitivity <value>

[SOURce]:FM: SENSitivity?

This command sets the frequency modulation deviation. This setting will be used if :FM:SOURce is set

to LFGenerator.

The variable <value> is expressed in units of Hertz.

*RST 1000

:FM:SENSitivity

[SOURce]:FM:SENSitivity <value>

[SOURce]:FM: SENSitivity?

This command sets the frequency modulation deviation per one volt peak amplitude signal input. This

setting will be used if :FM:SOURce is set to EXTernal.

The variable <value> is expressed in units of Hertz per Volt.

*RST 1000

:FM:INT:FREQuency

[SOURce]:FM:INT:FREQuency <value>

[SOURce]:FM:INT:FREQuency?

This command sets the frequency modulation rate in Hz. This setting will be used if :FM:SOURce is

set to INTernal.

The variable <value> is expressed in Hertz.

*RST 400

:FM:INT:SHAPe

[SOURce]:FM:INT:SHAPe RD|RU|SINE|SQUare|TRIangle

[SOURce]:FM:INT:SHAPe?

This command specifies the FM modulation shape. RD selects Ramp-Down and RU ramp up.

Standard waveforms available are SINE, SQUare and TRIangle.
