[:SOURce<hw>]:FREQuency:STEP[:INCRement] <Increment>
Sets the step width.
You can use this value to vary the RF frequency with command FREQ UP or FREQ
DOWN, if you have activated FREQ:STEP:MODE USER.
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
*RST: 1E6
Example: See Example "Frequency configuration" on page 1037
Manual operation: See "Variation Step" on page 433
13.18.7 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).

[:SOURce<hw>]:INPut:MODext:COUPling<ch> <Coupling>
Selects the coupling mode for an externally applied modulation signal.
Parameters:
<Coupling> AC | DC
AC
Passes the AC signal component of the modulation signal.
DC
Passes the modulation signal with both components, AC and
DC.
*RST: AC
Example:
INP:MOD:COUP AC
Selects the coupling mode AC for an externally applied modula-
tion signal.
