[SOURce]:FM Subsystem (Frequency Modulation)
Command Parameters Unit (default)
[SOURce:]FM:DEViation
[SOURce:]FM:SENSitivity 10000 Hz/V
[SOURce:]FM:INT:FREQuency
[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
[SOURce]:FM: SENSitivity?
This command sets the frequency modulation deviation. This setting will be used if :FM:SOURce is set to
LFGenerator.
The variable is expressed in units of Hertz.
*RST 10000
: FM:SENSitivity
[SOURce]:FM:SENSitivity
[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 is expressed in units of Hertz per Volt.
*RST 10000
: FM:INT:FREQuency
[SOURce]:FM:INT:FREQuency
[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 is expressed in Hertz.
*RST
: FM:SOURce
[SOURce]:FM:SOURce EXTernal | INTernal
[SOURce]:FM:SOURce?
This command selects the FM modulation signal source. If INTernal is selected, an internal modulation
source is applied. If EXTernal is selected, the device’s )M input (at the rear panel) is activated.
*RST EXT
: FM:STATe
[SOURce]:FM:STATe ON|OFF|1|0
[SOURce]:FM:STATe?
This command turns the frequency modulation on or off.
*RST OFF
:FM::COUPling
