Phase Modulation (PM)
l SCPI: PM:DEViation {<deviation_in_degrees>|MIN|MAX}
When the carrier is an arbitrary waveform, the deviation applies to the sample clock. Therefore, the effect on the full
arbitrary waveform is much less than that seen with standard waveforms. The extent of the reduction depends on the
number of points in the arbitrary waveform.
Modulating Source
The instrument accepts an internal or external modulation source.
l Modulating source: Internal (default), Other Channel, or External.
l With the External source, the carrier waveform is modulated with an external waveform. The ±5 V signal level
present on the rear-panel Modulation In connector controls the phase deviation. For example, if the deviation is
set to 180 degrees, a +5 V signal corresponds to a 180 degree phase shift. Lower levels produce less deviation.
