7.15.18 SOURce:PULM Subsystem
This subsystem contains the commands for setting the pulse modulation. The LF gen-
erator is used as the internal modulation source.
The pulse frequency of the internal rectangular signal is therefore set in the
SOURce:LFOutput subsystem.

[:SOURce<hw>]:PULM:POLarity <Polarity>
The command sets the polarity between modulating and modulated signal. This com-
mand is only effective for an external modulation signal.
Parameters:
NORMal|INVerted
NORMal
The RF signal is suppressed during the pulse pause.
INVerted
The RF signal is suppressed during the pulse.

*RST:
PULM:SOUR EXT
selects the external modulation source.
PULM:POL INV
selects inverted polarity.

Example:
[:SOURce<hw>]:PULM:SOURce <Source>
The command selects the source for pulse modulation.
Parameters:
INTernal|EXTernal|CODer
INTernal
The internally generated rectangular signal is used for the pulse
modulation. The frequency of the internal signal can be set in the
SOURce:LFOutput subsystem.
EXTernal
The signal applied externally via the EXT MOD connector is used
for the pulse modulation.
INTernal
<Source>
*RST:
PULM:SOUR INT
selects the internal modulation source.
PULM:STAT ON
activates the pulse modulation.
