[:SOURce]:PM[1]|2:SOURce?
This command sets the source to generate the phase modulation.
INT This choice selects internal source 1 or 2 to provide an ac-coupled signal.
EXT This choice selects the EXT 1 INPUT or the EXT 2 INPUT connector to
provide an externally applied signal that can be ac- or dc-coupled.
*RST INT
Remarks The externally applied, ac-coupled input signal is tested for a voltage
level and a display annunciator will report a high or low condition if
that voltage is >
±
3% of 1 V

Key Entry
ΦM Off On
Remarks The RF carrier is modulated when you set the signal generator’s
modulation state to ON, see :MODulation[:STATe]” on page 189 for
more information.
Whenever phase modulation is enabled, the
Φ
M annunciator is turned
on in the display
The two paths for phase modulation can be simultaneously enabled.
