:FM Subsystem
Using the command :FM[1]|2:INTernal[1]:FUNCtion:SHAPe SQUARe lets you specify
square as the amplitude modulation waveform for the
FM Path 1 and FM Path 2
configurations. Notice that the selected waveform applies only to whichever FM path
configuration you have currently selected.
Using the command :FM[1]|2:INTernal[1]:FUNCtion:SHAPe RAMP lets you specify ramp
as the amplitude modulation waveform for the
FM Path 1 and FM Path 2 configurations.
Notice that the selected waveform applies only to whichever FM path configuration you
have currently selected.
Using the command :FM[1]|2:INTernal[1]:FUNCtion:SHAPe NOISe lets you specify noise
as the amplitude modulation waveform for the
FM Path 1 and FM Path 2 configurations.
Notice that the selected waveform applies only to whichever FM path configuration you
have currently selected.
Using the command :FM[1]|2:INTernal[1]:FUNCtion:SHAPe DUALsine allows you to set
the dual sine as the amplitude modulation waveform for the
FM Path 1 and FM Path 2
configurations. In this mode you can set the FM rates for two separate tones. In addition,
you can set a percentage of the tone 2 FM depth to the total FM depth.
Using the command :FM[1]|2:INTernal[1]:FUNCtion:SHAPe SWEPtsine allows you to set
the swept-sine amplitude modulation waveform for the
FM Path 1 and FM Path 2
configurations. In this mode you can set the start and stop FM rate and the sweep time.
You can set the signal generator to a single, externally-triggered sweep on either a
negative or positive TTL level or you can choose continuous sweep, triggered immediately.
In this menu you can also select either a positive or negative polarity for the
TRIGGER OUT signal.
