Syntax
TRIGger:A:LOGIc:INPut?
Examples
TRIGGER:A:LOGIC:INPUT? might return :TRIGGER:A:LOGIC:IN PUT:CH1
HIGH;CH2 X;CH3 X
indicating that a logic high is expected on channel 1 while
channel 2 and channel three are “don't care.”
TRIGger:A:LOGIc:INPut:CH<x>
This command specifies the logical input condition for the channel specified
by <x>.

Trigger
Syntax
TRIGger:A:LOGIc:INPut:CH<x>
{HIGH|LOW|X}
TRIGger:A:LOGIc:INPut:CH<x>?
Arguments
HIGH specifies the logic high.
LOW specifies the logic low.
X specifies a "don't care" state.
Examples
TRIGGER:A:LOGIC:INPUT:CH1? might return :TRIGGER:LOG IC:INPUT:CH1
X
indicating that the setting for the A logic trigger input to channel 1 does not
matter.
TRIGGER:A:LOGIC:INPUT:CH2 HIGH sets the A logic trigger input to logic
HIGH for channel 2.
TRIGger:A:LOGIc:INPut:CLOCk:EDGE
Sets the polarity of the clock channel.

Commands Listed in Alphabetical Order
Arguments
RISe specifies t
o trigger on the rising or positive edge of a signal.
FALL specifies to trigger on the falling or negative edge of a signal.
TRIGger:A:LOGIc:INPut:CLOCk:SOUrce
This command specifies the channel to use as the clock source. The clock can
be selected as
NONE. A selection of None implies pattern trigger. Any other
selection implies state trigger.
Group

Syntax
TRIGger:A:LOGIc:INPut:CLOCk:SOUrce {CH1|CH2|CH3|CH4|
D0|D1|D2|D3|D4|D5|D6|D7|D8|D9|D10|D11|D12|D13|D14|D15|RF|NON E}
TRIGger:A:LOGIc:INPut:CLOCk:SOUrce?
Arguments
CH1–CH4 specifies an analog channel as the clock source.
D0–D15 specifies a digital channel as the clock source. (MSO/MDO4000/B models
only as well as MDO3000 and MDO400C models with option MDO3MSO or
MDO4MSO installed.)
RF specifies the internal RF power level as the clock source. (MDO4000/B/C
models only. Also requires installation of an MDO4TRIG application module.)
NONE specifies a Pattern trigger.
TRIGger:A:LOGIc:INPut:D<x>
This command specifies the logic pattern for a trigger on digital channel <x>,
where x is the channel number.
Group
Trigger
Syntax
TRIGger:A:LOGIc:INPut:D<x> {HIGH|LOW|X}
TRIGger:A:LOGIc:INPut:D<x>?
Arguments
High specifies the logic high state.
Low specifies the logic low state.
X specifies a "don't c
are" state.

GIc:INPut:RF
This command specifies the logic level to use when the internal RF power levelis
the source for a logic pattern trigger.
Conditions
MDO4000/B and MDO4000C with option SA3 or SA6 only. Also requires
installation of an MDO4TRIG application module.

TRIGger:A:LOGIc:PATtern:WHEn
Arguments
HIGH specifies to trigger on a high logic level.
LOW specifies to trigger on a low logic level.
X specifies a “don't care” condition.
Examples
TRIGger:A:LOGIc:INPut:RF HIGH spec
ifies to trigger on a high logic level
when the internal RF power level is the source for a logic pattern trigger.
TRIGger:A:LOGIc:INPut:RF? might r
eturn X, indicating that it doesn’t matter
whether the logic level is high or low.
TRIGger:A:LOGIc:PATtern? (Query Only)
Returns the conditions used for generating an A logic pattern trigger, with respect
to the defined input pattern, and identifies the time that the selected pattern may
be true and still generate the trigger.
