:PM[1]|2[:DEViation]:TRACk
Supported PSG-A Series
[:SOURce]:PM[1]|2[:DEViation]:TRACk ON|OFF|1|0
[:SOURce]:PM[1]|2[:DEViation]:TRACk?
This command enables or disables the deviation coupling between the paths (PM[1] and
PM2).
ON (1) This choice will link the deviation value of PM[1] with PM2; PM2 will
assume the PM[1] deviation value. For example, if PM[1] deviation is set
to 500 Hz and PM2 is set to 2 kHz, enabling the deviation tracking will
cause the PM2 deviation value to change to 500 Hz. This applies
regardless of the path (PM[1] or PM2) selected in this command.
OFF (0) This choice disables the coupling and both paths will have independent
deviation values.
*RST 0
Key Entry
ΦM Dev Couple Off On
Remarks This command uses exact match tracking, not offset tracking.
:PM[:DEViation]:STEP[:INCRement]
Supported PSG-A Series
[:SOURce]:PM[:DEViation]:STEP[:INCRement] <num>
[:SOURce]:PM[:DEViation]:STEP[:INCRement]?
This command sets the phase modulation deviation step increment.
The variable <num> sets the increment value in units of radians.
*RST
Ν/Α
Range 0.001–1E3
Key Entry
Incr Set
Remarks The value set by this command is used with the UP and DOWN choices
for the ΦM deviation command. Refer to “:PM[1]|2[:DEViation]” on
page 277 for more information.
The setting enabled by this command is not affected by signal
generator power-on, preset, or *RST.
Choices ON OFF 1 0
