Phase Modulation
Ext 1 DC-Coupled
This softkey lets you input an external, DC-coupled, phase modulation signal to
the EXT 1 INPUT connector.
The external 1 input has multiple uses but can be used for only one modulation at
a time. If, for example, you were using the external 1 input in an amplitude
modulation configuration for
AM Path 1, and then you configured ΦMPath2 to
also use the external 1 input, the signal generator would turn off
AM Path 1 and
assign the external 1 input to your
ΦMPath2 configuration. For the purposes of
this discussion, the external 1 AC-coupled input is the same as the external 1
DC-coupled source.
Softkey Location: Press
FM/ΦM hardkey, toggle FM/ΦM softkey to ΦM, press

Ext 2 AC-Coupled
This softkey lets you input an external, AC-coupled, phase modulation signal to
the EXT 2 INPUT connector. The modulation signal is tested for voltage and a
display annunciator will report a high or low condition if the voltage is >
±3% of
1Vpk.
The external 2 input has multiple uses but can be used for only one modulation at
a time. If, for example, you were using the external 2 input in an amplitude
modulation configuration for
AM Path 1, and then you configured ΦMPath2 to
also use the external 2 input, the signal generator would turn off
AM Path 1 and
assign the external 2 input to your
ΦMPath2 configuration. For the purposes of
this discussion, the external 2 AC-coupled input is the same as the external 2
DC-coupled source.
