G50 = 50 Ohm to ground
G600 = 600 Ohm to ground
HIGH = 100 kOhm to ground
*RST: HIGH
Example: See [:SOURce<hw>]:INPut:MODext:COUPling
on page 460.
Manual operation: See "Impedance" on page 104
[:SOURce]:INPut:TRIGger:SLOPe
<Slope>
Sets the polarity of the active slope of an applied instrument trigger.
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 "Trigger Slope" on page 133
12.15.5 SOURce:LFOutput subsystem
The SOURce:LFOutput subsystem contains the commands for setting the LF signal
source in CW and Sweep mode and for analog modulation.
Example: Setup an LF sweep
The following example shows a command sequence to set up an LF sweep.
// Reset the instrument to start from an initial state
*RST; *CLS
// Set the trigger mode, the sweep mode and the sweep range
TRIGger1:LFFSweep:SOURce SINGle
SOURce1:LFOutput1:SWEep:FREQuency:MODE AUTO
SOURce1:LFOutput1:FREQuency:STARt 1 kHz
SOURce1:LFOutput1:FREQuency:STOP 7 kHz
// Select linear spacing
// Select the waveform shape for the frequency sweep cycle
// Set the step width and the dwell time.
