Source:input Subsystem - R&S SMB100A Operating Manual

®
R&S SMB100A
Note: This value also applies to the step width of the rotary knob of the instrument and
increases or decreases the frequency accordingly, when you work in user-defined step
mode.
Parameters:
<Increment>
Example:
Manual operation:
[:SOURce<hw>]:FREQuency:STEP:MODE <Mode>
Activates (USER) or deactivates (DECimal) the user-defined step width used when
varying the frequency value with the frequency values UP/DOWN. The command is
linked to the command "Variation Active" for manual control, i.e. the command also
activates/deactivates the user-defined step width used when varying the frequency
value with the rotary knob.
Parameters:
<Mode>
Example:
Manual operation:

7.13.5 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:IMPedance
[:SOURce<hw>]:INPut:MODext:WIGNore
[:SOURce]:INPut:TRIGger:SLOPe
[:SOURce<hw>]:INPut:MODext:IMPedance <Impedance>
Sets the impedance for an externally applied modulation signal.

of setting
*RST: 1E6
FREQ:STEP 50 kHz
sets the step width for the frequency setting to 50 kHz.
See "Variation Step" on page 140
DECimal | USER
*RST: DECimal
FREQ:STEP 50 kHz
sets the step width for the frequency setting to 50 kHz.
FREQ:STEP:MODE USER
actives this step width for frequency variation with the rotary
knob (manual control) and with frequency values UP/DOWN
(remote control).
