1.
Turn on FM modulation using the SOURce[1|2]: FM:STAT
ON command.
2.
Use the APPLy command to select a carrier waveform.
Alternatively, the FUNC, FREQ, AMPl, and DCOffs
commands can be used to create a carrier waveform with
a designated frequency, amplitude and offset.
3.
Select an internal or external modulation source using the
SOURce[1|2]:FM:SOUR command.
4.
Use the SOURce[1|2]:FM:INT:FUNC command to select a
sine, square, upramp, dnramp or triangle modulating
waveshape. For internal sources only.
5.
Set the modulating frequency using the SOURce[1|2]:
FM:INT:FREQ command. For internal sources only.
6.
Use the SOURce[1|2]:FM:DEV command to set the
frequency deviation.
8-10-2. SOURce[1|2]:FM:STATe
Set
Query
Description Sets or disables FM modulation. By default FM modulation is
disabled. FM modulation must be enabled before setting other
parameters.
Note Burst or sweep mode will be disabled if FM modulation is
enabled. As only one modulation is allowed at any one time,
other modulation modes will be disabled when FM modulation
is enabled.
Syntax SOUR[1|2]:FM:STATe {OFF|ON}
Example SOUR1:FM:STAT ON
Enables FM modulation.
