Commands Listed in Alphabetical Order
TRIGger:A:LO
GIc:THReshold:(CH<x>|D<x>)
This command sets or queries the logic trigger threshold voltage for both analog
and digital channels (for MSO models), specified by x.
Group
Trigger
Syntax
TRIGger:A:LOGIc:THReshold: (CH<x>|D<x>) {<NR3>|ECL|TTL}
TRIGger:A:LOGIc:THReshold: (CH<x>|D<x>)?
Arguments
<NR3> specifi es the threshold voltage, in v olts.
ECL specifies a preset ECL high level of –1.3 V.
TTL specifies a preset TTL high level of 1.4 V.
Examples
TRIGGER:A:LOGIC:THRESHOLD: CH2 3.0E-3 sets the A logic trigger threshold
voltage for Channel 2 to 3 mV.
TRIGGER:A:LOGIC:THRESHOLD: CH3? might return
:TRIGGER:A:LOGIC:THRESHOLD :CH3 1.2000E+00, indicating that the A
logic trigger threshold voltage for Channel 3 is 1.2 V.
TRIGger:A:LOWerthreshold:CH<x>
Sets or returns the lower threshold for the channel selected. Each channel can
have an independent level. Used in Runt and Slew Rate triggers as the lower
threshold. Used for all other trigger types as the single level/threshold.
Group
