5.7.4 Modulating Waveform Source
Press
Mod
->
Source
to select Internal (default) or External as the modulation source.
Internal Source
When internal modulation source is selected, the modulating waveform is set as a Square with
50% duty cycle, and the rate at which the output phase "shifts" between "carrier phase" and
"modulating phase" is determined by "2PSK Rate".
External Source
With the External source, the generator receives the external modulating signal from the
[Sync/Mod/Trig]
connector at the front panel.
Note: The
[Sync/Mod/Trig]
connector is different when controlling 2PSK and AM/FM/PM
modulations externally. In 2PSK modulation, the
[Sync/Mod/Trig]
connector has adjustable edge
polarity.
5.7.5 2PSK Rate
When internal modulation source is selected, the 2PSK Rate is the rate at which the output phase
shifts between "carrier phase" and "modulating phase". Press
Rate
to set.
Use the numeric keyboard or direction keys and knob to input the desired frequency value.
The frequency range is from 2mHz to 1MHz and the default is 100Hz.
Note: This menu will be grayed out and disabled when the external modulation source are
selected.
5.7.6 Modulating Phase
Press
Phase
on modulation menu
to set the parameter.
Use the numeric keyboard or direction keys and knob to input the desired amplitude value.
