[:SOURce<hw>]:FREQuency:STEP:MODE <Mode>
This command activates (USER) or deactivates (DECimal) the user-defined step width
used when varying the frequency value with the frequency values UP/DOWN. The com-
mand 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.
In the case of two-path instruments, the step width can be set separately for each path.
Parameters:
DECimal|USER
DECimal
<Mode>
*RST:
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).
Example:
7.15.8 SOURce:INPut Subsystem
The SOURce:INPut subsystem contains the commands for configuring the inputs for
trigger, data and control signals. A common trigger threshold and input impedance is
effective for all trigger and control signal inputs.
In case of a two-path instrument, this affects both paths.
The settings influence the digital modulations, the generation of waveforms or multicarrier
signals, and all digital standards. Irrespective of this, a common threshold and input
impedance is effective for the serial and parallel data input (Path A only). These data
sources are available for digital modulation ("Custom Digital Modulation").

[:SOURce]:INPut:DATA:IMPedance <Impedance>
The command sets the impedance of all data inputs.
The setting affects the serial data input DATA at the front of the instrument and the serial
data inputs DATA at the AUX I/O interface at the rear of the instrument.
