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> float
Range:
full frequency range
Increment: see the data sheet: RF characteristics > Resolution
of setting
*RST: 1E6
Example: FREQ:STEP 50 kHz
sets the step width for the frequency setting to 50 kHz.
Manual operation: See "Variation Step" on page 204
[: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> DECimal | USER
*RST:
DECimal
Example: 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).
Manual operation: See "Variation Active" on page 204
7.16.7 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.
The settings influence the digital modulations, the generation of waveforms or multicar-
rier 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").
