Hardkey and Softkey Reference
Phase Modulation
ΦM Off On
This softkey toggles the phase modulation on or off for whichever ΦM
configuration (
ΦMPath1 or ΦMPath2) you have selected. Notice, however that
although you can turn on phase modulation with this softkey, the RF carrier is
modulated by the enabled modulation only when you have also set
Mod On/Off to
On. Whenever phase modulation is enabled, the ΦM annunciator is turned on in the
display.
There are two paths for
ΦM modulation which can be simultaneously enabled as
long as they use different sources (Int, Ext1, or Ext2).
ΦMPath2 is limited to a
maximum rate of 1 MHz.
ΦMPath2 must be set to a deviation less than or equal
to
ΦMPath1. The modulation signals from both paths are summed internally for
composite modulation.
Softkey Location: Press
