[SOURce:]FM:INT:FREQuency <value> 400 Hz
[SOURce:]FM:INTernal:SHAPe RD|RU|SINE|SQUare|TRIangle SINE
[SOURce:]FM:SOURce INTernal | EXTernal EXT
[SOURce:]FM:STATe ON|OFF|1|0 OFF
[SOURce:]FM:COUPling DC | AC AC
: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.
