[:SOURce<hw>]:FREQuency:STEP[:INCRement]
<Increment>
Sets the step width.
You can use this value to vary the RF frequency with command
Note:
This value also applies to the step width of the rotary knob on the instrument
and, in user-defined step mode, increases or decreases the frequency.
Parameters:
<Increment>
float
Range:
0 Hz to RFmax - 100 kHz
Increment: 0.01 Hz

12.15.4 SOURce:INPut Subsystem
The
SOURce:INPut
subsystem contains the commands for configuring the inputs for
external modulation signals. The instrument trigger setting influences all sweeps and is
effective in the List mode (Instrument Trigger).
