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 124
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
(Instrument Trigger).
[:SOURce<hw>]:INPut:MODext:IMPedance......................................................................298
[:SOURce]:INPut:TRIGger:SLOPe................................................................................... 298
[:SOURce<hw>]:INPut:MODext:IMPedance <Impedance>
Sets the impedance for an externally applied modulation signal.
Parameters:
<Impedance> HIGH | G600
HIGH
> 100 k0hm to ground
*RST: HIGH
Example:
INP:MOD:IMP HIGH
sets > 100 kOhm to ground.
Manual operation: See "Ext. Impedance" on page 172
[:SOURce]:INPut:TRIGger:SLOPe <Slope>
Sets the polarity of the active slope of an externally applied trigger signal at the trigger
input (BNC connector at the rear of the instrument).
The setting is effective for both inputs at the same time.
Parameters:
<Slope> NEGative | POSitive
*RST: POSitive
Example:
INP:TRIG:SLOP NEG
Activates the falling slope of the external trigger signal at the
trigger input.
Manual operation: See "Ext. Trigger Input Slope" on page 163
