387 Operating Manual 1407.0806.32 ─ 21
Example: POW:STEP 2
sets the step width for the level setting to 2 dB.
POW:STEP:MODE USER
actives this step width for level variation with the rotary knob
(manual control) and with level values
UP/DOWN
(remote con-
trol).
Manual operation: See "Variation Active" on page 150
[: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
value and this stop value.
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> float
Determines the last level value of the sweep setting range.
Range:
full specified level range
Increment: see the data sheet: Level sweep > Step size setting
resolution
*RST: -10
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 186
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.
