Branches to a specified block when a specified trigger event occurs. If the event has not yet occurred when the 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 when a measurement meets preset limit criteria. The limit type can be above, below, inside, or outside the specified limits.

:TRIGger:BLOCk:BRANch:LIMit:CONStant 5, OUTside, 0.15, 0.65, 8
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 is encountered in the trigger model.

:TRIGger:BLOCk:BRANch:ONCE <blockNumber>, <branchToBlock>
: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 the first time it is encountered, then branches to the specified block on subsequent encounters.

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

Defines a trigger model block that clears the reading buffer. When execution reaches this block, the instrument empties the specified buffer; if no buffer is given, defbuffer1 is used.

: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. If two lists are specified, the settings are recalled from the next index in both lists, and the second list must be the opposite type of the first.

:TRIGger:BLOCk:CONFig:NEXT <blockNumber>, "<configurationList>"
:TRIGger:BLOCk:CONFig:NEXT <blockNumber>, "<configurationList>", "<configurationList2>"

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, both are recalled from the previous index when the block is reached.

TRIG:BLOC:CONF:PREV 14, "SETTINGS_LIST"

Recalls the system settings stored in a source or measure configuration list. If an index is supplied, that specific configuration list entry is recalled; otherwise the default index is 1.

TRIG:BLOCK:CONF:RECALL 1, "biasLevel", 1

Adds a constant delay to the execution of a trigger model.

:TRIGger:BLOCk:DELay:CONStant <blockNumber>, <time>

Adds a user delay to the execution of the trigger model. The delay block stops normal measurement and trigger model operation for the time set by the specified user-delay entry, while background measurements continue.

:TRIG:BLOC:DEL:DYN 2, SOUR1 Set trigger block 2 to a dynamic delay that calls source user
notes":"The user-delay command referenced is only available over a remote interface."}】`】```

Defines a trigger model block that sets the lines on the digital I/O port high or low. The bit pattern is an integer value; the optional bit mask controls which lines are driven.

:TRIG:BLOC:DIG:IO 4, 20, 60

Returns the settings for all trigger model blocks.

:TRIG:BLOC:LIST?

Allows you to log an event in the event log when the trigger model is running.

::TRIGger:BLOCk:LOG:EVENt <blockNumber>, <eventNumber>, "<message>"

Defines a trigger block that makes or digitizes a measurement. The block stores readings in the specified buffer and can optionally take a count of readings to make before advancing.

:TRIGger:BLOCk:MDIGitize <blockNumber>
:TRIGger:BLOCk:MDIGitize <blockNumber>, "<bufferName>"
:TRIGger:BLOCk:MDIGitize <blockNumber>, "<bufferName>", <count>

Creates a placeholder block that performs no action in the trigger model. This command is available only through remote commands.

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

:TRIG:BLOC:NOT 5, 2

Defines a trigger block that turns the output source on or off when the trigger model reaches the block. When listed in trigger blocks, it appears as SOURCE_OUTPUT.

TRIG:BLOC:SOUR:STAT 1, 1
TRIG:BLOC:DEL:CONS 2, 0.01
TRIG:BLOC:MDIG 3
TRIG:BLOC:BRAN:COUN 4, 100, 2
TRIG:BLOC:SOUR:STAT 5, 0

Defines a trigger model wait block that pauses until a specified event occurs before allowing execution to continue. Optional clear and logic/event arguments control whether previously detected events are cleared and whether one or multiple events must occur.

:TRIGger:BLOCk:WAIT 9, DISP

Determines the trigger mode setting after bootup. The setting can disable continuous measurements, enable them automatically, or place the instrument in local control and start them after bootup.

TRIG:CONT OFF

Clears the trigger event on the specified digital input line. It clears the event detector, discards the history, and sets the overrun status to 0.

:TRIG:DIG2:IN:CLE

Sets the edge used by the trigger event detector on the specified digital trigger line. The command is also queryable to read back the current edge setting.

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

Returns the event detector overrun status for the specified digital I/O trigger line. The status is returned as 0 (false) or 1 (true), indicating whether an event was ignored because the detector was already in the detected state.

TRIG:DIG1:IN:OVER?

Sets the output logic of the trigger event generator for the specified digital I/O trigger line. Positive asserts a TTL-high pulse; negative asserts a TTL-low pulse.

:TRIG:DIG4:OUT:LOG NEG

Sets the length of time that the specified digital trigger line is asserted for output triggers. The command is also queryable to read back the pulse width.

Selects the event that causes a trigger to be asserted on the specified digital output line. The trigger stimulus for a digital I/O line can be set to one of the trigger events listed in the manual.

:TRIGger:DIGital<n>:OUT:STIMulus <event>
:TRIGger:DIGital<n>:OUT:STIMulus?

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

:TRIG:LAN5:IN:CLE

Sets the trigger operation and detection mode of the specified LAN event. The mode determines whether the trigger detector responds to rising, falling, or either edge.

:TRIG:LAN2:IN:EDGE FALL

Indicates the overrun status of the specified LAN event detector.

Prepares the event generator for outgoing trigger events. When set to ON it sends event messages and opens the TCP connection for TCP connections; when set to OFF it closes the TCP connection.

: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 for outgoing trigger events. After changing this setting, the connect command must be sent before outgoing messages can be sent.

TRIG:LAN1:OUT:IP:ADDR "192.0.32.10"

Sets the logic used by the trigger event detector and the output trigger generator on the specified LAN trigger line.

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

Sets the LAN protocol used for sending trigger messages on the specified LAN event. The supported protocols are TCP, UDP, and MULTicast.

:TRIG:LAN1:OUT:PROT TCP Set the LAN protocol for trigger messages to be TCP and
notes

Specifies which LAN event causes this trigger to assert. Setting it to NONE disables automatic trigger generation.

TRIG:LAN1:OUT:STIM TIM1

Pauses a running trigger model. To continue the trigger model, send the resume command.

INIT Start a trigger model, then pause and resume it.
TRIG:PAUS
TRIG:RES
*WAI

Continues running a paused trigger model operation.

:TRIGger:RESume
TRIG:RES

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

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. A count of 0 makes the timer generate trigger events indefinitely.

:TRIGger:TIMer<n>:COUNt <count>
:TRIGger:TIMer<n>:COUNt?

Sets and reads the timer delay. The delay is the period after the timer is triggered and before it generates a trigger event.

TRIG:TIM2:DEL 50E-6

Configures the timer start time in fractional seconds. When the timer is enabled, it starts immediately if the configured start time is in the past or in the future.

TRIG:TIM1:STAR:SEC 60
TRIG:TIM1:START:FRAC 0.5

Specifies when timer events are generated for the selected trigger timer. The setting can be configured to generate an event when the delay elapses or both when the timer starts and when the delay elapses.

Indicates whether an event was ignored because the event detector was already in the detected state when the event occurred. Returns 0 if there is no overrun or 1 if there is an overrun.

TRIG:TIM1:STAR:OVER? Checks the overrun status on trigger timer 1.

Configures the start time for trigger timer <n>. If the timer is enabled and the configured start time has already passed, the timer starts immediately.

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

This command describes the event that starts the trigger timer. Set the stimulus to a trigger event to start the timer when that event occurs, or to none to disable event processing and use the timer based on the start time.

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