Command
Description
TRIGger:A:LEVel:CH<x> S ets the threshold voltage level for an Edge, Pulse Width, Runt or Rise/Fall
(aka Transition, aka Slew Rate) trigger to use w hen triggering on an analog
channel waveform.
TRIGger:A:LEVel:D<x> Sets the threshold voltage level for an Edge, Pulse Width, Runt or Rise/Fall
(aka Transition, aka Slew Rate) trigger to use when triggering on a digital
channel waveform.
TRIGger:A:LOGIc?
Returns all A trigger logic settings
TRIGger:A:LOGIc:CLAs s This command sets the class of the logic trigger (either logic or setup/hold).
You also need to set the trigger type using the command T RIGger:A:TYPe.
TRIGger:A:LOGIc:FU NCtion This command specifies the logical combination of the input channels for the A
logic trigger
TRIGger:A:LOGIc:INPut? Returns the logic input values for all channels
TRIGger:A:LOGIc:INPut:C H<x> Specifies or returns the logic setting for the specified channel
TRIGger:A:LOGIc:INPut:C LOCk:EDGE Sets the polarity of the clock channel
TRIGger:A:LOGIc:INPut:C LOCk:SOUrce This command specifies the channel to use as the clock source
TRIGger:A:LOGIc:INPut:D <x> This command specifies the logic pattern for a trigger on digital channel <x>
TRIGger:A:LOGIc:INPut:R F This command specifies the logic level to use when the internal RF power level
is the source for a logic pattern trigger.
TRIGger:A:LOGIc:PATtern? Returns the conditions for generating an A logic pattern trigger
TRIGger:A:LOGIc:PATtern:DELTatime This command specifies the pattern trigger delta time value
TRIGger:A:LOGIc:PATtern:WHEn This command specifies the pattern logic condition on which to trigger the
oscilloscope
TRIGger:A:LOGIc:THReshold:CH<x> Sets or queries the trigger A logic threshold voltage for the specified channel.
TRIGger:A:LOGIc:THReshold:RF This command specifies the threshold to use when the internal RF power level
is the source for a logic trigger. It will affect all trigger types using the channel.
TRIGger:A:LOGIc:THReshold:D<x> This command specifies the trigger A logic threshold level for the speci fied
digital channel.
TRIGger:A:LOWerthreshold:CH<x> This command specifies the lower threshold for the channel selected.
TRIGger:A:LOWerthreshold:D<x> Sets the A trigger lower threshold for the digital channel selected.
TRIGger:A:LOWerthreshold{:AUX|:EXT} This command specifies the lower threshold for the Aux Input connector.
TRIGger:A:LOWerthreshold:RF This command specifies the lower threshold when using the internal RF power
level for a RUNT trigger, or the single threshold in the cases of the PULSE
and TIMEOUT triggers.
TRIGger:A:MO De This command specifies the A trigger mode – either AUTO or NORMAL.
TRIGger:A:PULse:CLAss This command specifies which kind of pulse to trigger on (either runt, width,
transition (rise/fall or slew rate) or timeout). You also need to set the trigger
type to
PULSe using the command TRIGger:A:TYP e.
TRIGger:A:PULS EW idth:HIGHLimit This command specifies the upper limit to use, in seconds, w hen triggering
on detection of a pulse whose duration is inside or outside a range of two
values. (Use TRIGger:A:PULSEWidth:LOWLimit to specify the lower value
of the range.)
