Stops all trigger model commands on the instrument. When received, the instrument stops the trigger model.

:ABORt

Starts the trigger model.

INIT
*WAI

Clears the blender event detector and resets the overrun indicator of blender <n>. The detector is set to the undetected state.

:TRIG:BLEN2:CLE Clears the event detector for blender 2.

Selects whether the blender performs OR operations or AND operations. The setting is saved with settings recall and is affected by instrument reset, power cycle, and trigger blender clear.

:TRIG:BLEN2:CLE

Indicates whether an event was ignored because the event detector was already in the detected state when the event occurred. It reports only the state of the event detector built into the event blender, not overruns elsewhere in the trigger model.

:TRIG:BLEN1:OVER? If an event was ignored, the output is 1.

Specifies the event used to trigger blender input <m> of blender <n>. The event can be set to none to disable the blender input.

Defines a trigger model block that always branches to a specific block. When the trigger model reaches this block, it goes to the block specified by the branch target.

TRIG:BLOC:BRAN:ALW 9, 20

Defines a trigger model block that branches to a specified block a specified number of times.

:TRIGger:BLOCk:BRANch:COUNter <blockNumber>, <targetCount>, <branchToBlock>
TRIG:BLOC:BRAN:COUN 3, 5, 2
TRIG:BLOC:BRAN:COUN 5, 3, 2

Returns the count value of the trigger model counter block. If the counter is active, it returns the present count; if the trigger model has started or is running but has not yet reached the counter block, the value is 0.

TRIG:BLOCK:BRAN:COUN:COUN? 4

Creates a block in the trigger model that resets a branch counter to 0. When the trigger model reaches this block, it resets the count of the specified Branch on Counter block to zero.

:TRIG:BLOC:BRAN:COUN:RES 6, 3

Defines a trigger model block that branches to a specified block when the difference between two measurements meets the preset criteria. The block subtracts the most recent measurement from the previous measurement and compares the result to the target difference.

TRIG:BLOC:BRAN:DELT 5, 0.5, 7, 4

Branches to a specified block when a specified trigger event occurs. If the event has not yet occurred when the trigger model reaches the branch-on-event block, execution continues in normal sequence until the next time the block is reached after the event occurs.

Defines a trigger model block that branches to a specified block if a measurement meets preset constant-limit criteria.

:TRIGger:BLOCk:BRANch:LIMit:CONStant 5, OUTside, 0.15, 0.65, 8

Defines a trigger model block that branches to a specified block if a measurement meets user-defined dynamic limit criteria.

Causes the trigger model to branch to a specified building block the first time it encounters this block. If the block is encountered again, the trigger model ignores it and continues in the normal sequence until the trigger model returns to idle.

:TRIG:BLOC:BRAN:ONCE 2, 4

Causes the trigger model to go to a specified building block every time it encounters that block, except for the first time. The branch-once-excluded block is ignored on first encounter and reset when the trigger model starts or is placed in idle.

:TRIG:BLOC:BRAN:ONCE:EXCL 2, 4

Defines a trigger model block that clears the reading buffer.

:TRIGger:BLOCk:BUFFer:CLEar <blockNumber>
:TRIGger:BLOCk:BUFFer:CLEar <blockNumber>, "<bufferName>"

Recalls the settings at the next index of a source or measure configuration list when the trigger model reaches this block. If two configuration lists are supplied, both are recalled from their next index and the second list must be the opposite type of the first.

TRIG:BLOC:CONF:NEXT 12, "SETTINGS_LIST"
:TRIG:BLOC:CONF:NEXT 7, "measTrigList", "sourTrigList"

Defines a trigger model block that recalls the settings stored at the previous index in a source or measure configuration list. If both source and measure configuration lists are specified, each is recalled from its previous index when the block is reached.

Recalls system settings stored in a source or measure configuration list when the trigger model reaches the block. You can optionally specify an index to recall a specific set of configuration settings.

Adds a constant delay to the execution of a trigger model. When execution reaches a delay block, it waits for the specified time before proceeding to the next block.

Adds a user delay to the execution of the trigger model. When execution reaches a dynamic delay block, it pauses normal measurement and trigger model operation for the time set by the delay while background measurements continue.

Defines a trigger model block that sets the digital I/O port lines high or low. The block is specified by a sequence number plus a bit pattern, with an optional bit mask to select which lines are driven.

:TRIGger:BLOCk:DIGital:IO <blockNumber>, <bitPattern>
:TRIGger:BLOCk:DIGital:IO <blockNumber>, <bitPattern>, <bitMask>

Returns the settings for all trigger model blocks.

:TRIG:BLOC:LIST?

Logs an event in the event log when trigger model execution reaches the specified block. The command can log information, warning, error, or abort events, and the abort option immediately aborts the trigger model.

TRIGger:BLOCk:LOG:EVENt 9, INFO2, "Trigger model complete"

Defines a trigger block that makes or digitizes a measurement. The block stores readings in a specified buffer and can use a specified count, including INF, 0, or AUTO.

TRIG:LOAD "EMPTY" Reset trigger model settings.
TRIG:BLOC:BUFF:CLE 1, "defbuffer2" Clear defbuffer2 at the beginning of the trigger model.
TRIG:BLOC:MDIG 2, "defbuffer2" Set the measurements to be stored in defbuffer2.
TRIG:BLOC:BRAN:COUN 3, 5, 2 Loop and make five readings.
TRIG:BLOC:DEL:CONS 4, 1 Delay 1 s.
TRIG:BLOC:BRAN:COUN 5, 3, 2 Loop three more times back to block 2.
TRIG:BLOC:CONF:NEXT 1, "countactive"
TRIG:BLOC:MDIG 2, "defbuffer1", AUTO
TRIG:BLOC:DEL:CONS 3, 1
TRIG:BLOC:BRAN:COUN 4, 3, 1

Creates a placeholder block that performs no action in the trigger model. It is available only using remote commands.

TRIG:BLOC:NOP 5 Set block number 5 to be a no operation block.

Defines a trigger model block that generates a trigger event and immediately continues to the next block.

TRIG:BLOC:NOTify 5, 2

Defines a trigger block that turns the output source on or off. The block determines whether the source output is enabled when the trigger model reaches it.

:TRIGger:BLOCk:SOURce:STATe <blockNumber>, <state>
TRIG:BLOC:SOUR:STAT 1, 1
TRIG:BLOC:SOUR:STAT 5, 0

Defines a trigger model block that waits for an event before allowing the trigger model to continue.

:TRIGger:BLOCk:WAIT 9, DISP

Determines the trigger mode setting after bootup. The setting can be OFF, AUTO, or RESTart; RESTart places the instrument into local control and starts continuous measurements after bootup.

TRIG:CONT OFF

Clears the trigger event on a digital input line. It clears the event detector, discards the history, and clears the overrun status for the specified trigger line.

:TRIG:DIG2:IN:CLE

Sets the edge used by the trigger event detector on the specified digital trigger line. The query returns the currently selected edge.

:TRIG:DIG2:IN:EDGE FALL
:TRIG:DIG2:IN:EDGE?

Returns the event detector overrun status for the specified digital trigger line. The status is reported as 0 (false) or 1 (true).

Sets the output logic of the trigger event generator for the specified digital I/O trigger line to positive or negative. The query form returns the current output logic.

:TRIG:DIG4:OUT:LOG NEG

Describes the length of time that the trigger line is asserted for output triggers. Setting the pulse width to zero asserts the trigger indefinitely.

TRIG:DIG1:OUT:PULS 2

Selects the event that causes a trigger to be asserted on the specified digital output line. This command can be set and queried.

:TRIG:DIG2:OUT:STIMulus TIM3

Clears the event detector for a LAN trigger. It discards the trigger packet history and clears all overruns associated with the specified LAN trigger.

:TRIG:LAN5:IN:CLE

Sets the trigger operation and detection mode of the specified LAN event. The command controls how the trigger event detector and output trigger generator operate on that trigger.

Indicates whether the specified LAN event was ignored because the event detector was already in the detected state when the event occurred. The trigger overrun state for the LAN packet is returned as 1 (true) or 0 (false).

TRIG:LAN5:IN:OVER?

Prepares the event generator for outgoing trigger events. Setting it to ON prepares the generator to send event messages; for TCP connections it opens the TCP connection, and OFF closes it.

:TRIGger:LAN1:OUT:PROTocol MULT Set the protocol to multicast and prepare the event
:TRIGger:LAN1:OUT:CONNect:STATe ON generator to send event messages.

Specifies the address, in dotted-decimal format, of UDP or TCP listeners.

Sets the logic used by the trigger event detector and the output trigger generator on the specified LAN trigger line. The setting is saved in recall/save settings and survives instrument reset and power cycle.

TRIG:LAN1:OUT:LOG POS Set the logic to positive.

Sets the LAN protocol used for sending outgoing trigger messages, and the setting is saved with recall/save settings. The LAN event number n is 1 to 8, and the protocol can be TCP, UDP, or MULTicast.

Specifies which LAN event causes trigger output stimulus to assert for trigger packet <n>. Setting the event to NONE disables automatic trigger generation.

TRIG:LAN1:OUT:STIM TIM1

Pauses a running trigger model. Send :TRIGger:RESume to continue the trigger model.

INIT
TRIG:PAUS
TRIG:RES
*WAI

Continues a paused trigger model. If the trigger model was paused, this command resumes running the trigger model operation.

TRIG:RES

Returns the present state of the trigger model. The instrument returns the trigger state and the block that the trigger model last executed.

:TRIG:STAT? An example output if the trigger model is inactive and ended at
block 9 is:
IDLE;IDLE;9

Clears the timer event detector and overrun indicator for the specified trigger timer number.

:TRIG:TIM1:CLE Clears trigger timer 1.

Sets the number of events to generate each time the timer generates a trigger event or is enabled as a timer or alarm. The query returns the present count value.

:TRIG:TIM2:COUN 4
:TRIG:TIM4:COUN 20

Sets and reads the timer delay. The returned value is the delay interval that will be used the next time the timer is triggered.

TRIG:TIM2:DEL 50E-6

Configures the alarm of the timer, or a time in the future when the timer will start. If the timer is enabled, it starts immediately when configured for a start time in the past or future.

Specifies when trigger timer events are generated. When set ON or 1, a trigger event is generated immediately when the timer is triggered and again when the delay elapses; when set OFF or 0, the event is generated only when the timer elapses.

TRIG:TIM3:STAR:GEN ON Set trigger timer 3 to generate an event when the timer starts and when the timer delay elapses.

Indicates whether a start event was ignored because of the event detector state.

Configures the alarm or future start time for the selected trigger timer. When the timer is enabled, it starts immediately if the configured start time has already passed.

TRIG:TIM1:STAR:SEC 60
TRIG:TIM1:STAR:FRAC 0.5
TRIG:TIM1:STAT ON

Sets or queries the event that starts trigger timer <n>. The stimulus can be any trigger event, or NONE to disable event processing and use the timer as a timer or alarm based on the start time.

:TRIGger:TIMer<n>:STARt:STIMulus <event>
:TRIGger:TIMer<n>:STARt:STIMulus?

Enables or disables the trigger timer. When enabled, the timer performs the delay operation; when disabled, there is no timer on the delay operation.

:TRIGger:TIMer<n>:STATe <state>
:TRIGger:TIMer<n>:STATe?
