Phase Modulation
ΦM Path 1 2
Use ΦMPath1 and ΦMPath2 to define two unique phase modulation
configurations. For example, select
ΦMPath1 (ΦMPath1 is the default after a
normal preset. If
ΦMPath1 is not highlighted, press the softkey once and the
selection will toggle from
ΦMPath2 to ΦMPath1.) Configure the modulation
characteristics (such as deviation, source, rate, and waveform) using the
remaining softkeys in the
ΦM menu. Then enable ΦM by setting ΦMOffOn to On.
To configure a second phase modulation configuration, toggle to
ΦMPath2.
Define the modulation characteristics for this second configuration and enable
ΦM by setting ΦMOffOn to On.
The RF carrier is available at the RF OUTPUT connector when you set
RF On/Off
to
On. Set Mod On/Off to On to modulate the RF carrier with the modulations that
you have enabled.
ΦM Path 1 and ΦM Path 2 are summed internally for composite modulation. Either
path can be switched to any one of the modulation sources: Int, Ext1, or Ext2. All
modulation types can be simultaneously enabled, except FM with
ΦM. AM, FM,
and
ΦM can sum simultaneous inputs from any two sources (Int, Ext1, and Ext2).
Any given source (Int, Ext1, or Ext2) can only be routed to one activated
modulation type.
Softkey Location: Press
FM/ΦM hardkey, toggle FM/ΦM softkey to ΦM, press
ΦMPath12
Status after Normal Preset: ΦM Path 1
