ESG Family Signal Generators Programming Commands and Examples
:PM Subsystem
*RST Value: 0.000 radians
Φ Modulation Deviation Coupling
:PM[1]|2[:DEViation]:TRACk ON|OFF|1|0
:PM[1]|2[:DEViation]:TRACk?
This command allows the phase modulation deviation values on both path 1 and path 2 to
track each other. The choices are On (1) or Off (0). If the phase modulation deviation
coupling function is activated, changing the phase modulation deviation on path 1 will
change the in phase modulation deviation on path 2 to match, and visa versa. This is an
exact match tracking, not an offset tracking.
*RST Value: Off
Φ Modulation Source
:PM[1]|2:SOURce INT[1]|EXT1|EXT2
:PM[1]|2:SOURce?
This command sets the source that will generate the phase modulation. The choices are
Internal Source 1, External Source 1, or External Source 2.
*RST Value: Internal
Φ Modulation State
:PM[1]|2:STATe ON|OFF|1|0
:PM[1]|2:STATe?
This command sets the operating state of the phase modulation source. The choices are On
(1) or Off (0).
*RST Value: Off
