Example:
Manual operation:
[:SOURce<hw>]:POWer:STOP <Stop>
Sets the stop level for the RF sweep.
Note: You can select any level within the setting range. The range is defined by the
SOURce<hw>]:POWer:STARt
A defined offset ([:SOURce<hw>]:POWer[:LEVel][:IMMediate]:OFFSet)
affects the level values according to the formula:
Minimum level + OFFSet ... Maximum level + OFFSet
Parameters:
<Stop>
Example:
Manual operation:

7.13.13 SOURce:PULM Subsystem

This subsystem contains the commands for setting the pulse modulation.
The LF generator is used as the internal modulation source. The pulse frequency of
the internal rectangular signal is therefore set in the SOURce:LFOutput subsystem.
The external signal is input at the PULSE EXT connector. The connector can be used
as trigger input for internal pulse modulation. The polarity and input impedance of the
connector can be selected. The pulse modulation signal is output at the PULSE VIDEO
connector.
Programming Examples
Example: Performing pulse modulation
This example shows a command sequence to perform pulse modulation.
