[:SOURce]:INPut:TRIGger:LEVel <Level>
Sets the high/low threshold of the trigger and control signal inputs in the baseband sec-
tion. In the case of positive polarity, this threshold determines the point as of which a
signal is high (active) or low (inactive).
The command affects:
●
TRIGGER inputs
●
CLOCK inputs
●
CW, BURST, and LEV_ATT inputs (AUX I/O connector)
Parameters:
<Level> float
Range:
0.01 to 2
Increment: 0.01
*RST:
1
Default unit: V
Example: INP:TRIG:LEV 1 V
a high/low threshold of 1 volt is set at all trigger and control sig-
nal inputs of the baseband section. In the case of positive polar-
ity, the signal is high (active) for a signal voltage of 1 volt and
higher.
Manual operation: See "Threshold Trigger/Control Input" on page 142
[: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).
Parameters:
<Slope> NEGative | POSitive
*RST:
POSitive
Example: INP:TRIG:SLOP NEG
activates the falling slope of the external trigger signal at the trig-
ger input.
Manual operation: See "Instrument Trigger Input Slope" on page 143
