[: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 454
Manual operation: See "Variation Step" on page 62
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).

[:SOURce<hw>]:INPut:MODext:COUPling <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:
SOURce1:INPut:MODext:COUPling AC
SOURce1:INPut:MODext:IMPedance G50
Manual operation: See "Coupling (AC/DC)" on page 104
[:SOURce<hw>]:INPut:MODext:IMPedance<ch> <Impedance>
Sets the impedance for the externally supplied modulation signal.
