Example:
POW:STOP 3
sets the stop level for the level sweep to 3 dBm for RF output A.
Manual operation: See " Stop Level - Level Sweep " on page 167
7.13.12 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.
