Syntax
TRIGger:A:SETHold:THResho ld:CH<x> {<NR3>|ECL|TTL}
TRIGger:A:SETHold:THResho ld:CH<x>?
Arguments
<NR3> specifies the threshold voltage, in volts.
ECL specifies a preset ECL high level of –1.3 V.
TTL specifies a preset TT L high level of 1.4 V.
Examples
TRIGGER:A:SETHOLD:THRESHO LD:CH1 1.5 sets the channel 1 threshold
to 1.5 volts.
TRIGGER:A:SETHOLD:THRESHO LD:CH1? might return
TRIGGER:A:SETHOLD:THRESHO LD:CH1 0.0E+0 indicating that the
channel 1 threshold is set to 0.0 volts.
TRIGger:A:SETHold:THReshold:D<x>
Sets the Threshold for the Selected Digital Channel. Affects all trigger types
using the Digital Channel.
