Export Signal (G Dataflow)

Last Modified: May 16, 2018

Routes signals (clocks, triggers, and events) to the output terminal you specify.

Any routes created within a session persist after the session closes to prevent signal glitching.

Programming Patterns

To unconfigure signal routes created in previous sessions, set the reset device input of Initialize With Channels to True or use Reset Device.

output terminal

Terminal to export the signal (clock, trigger, or event).

Refer to the Device Routes tab in MAX for a complete list of the output terminals available on your waveform generator, or, for PXIe-5413/5423/5433 waveform generators, refer to the Routes topic for your waveform generator in the PXI Waveform Generator Manual.

Default: Do not export

datatype_icon

session in

Handle that identifies your instrument session previously allocated by Initialize With Channels.

datatype_icon

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

datatype_icon

signal identifier

Identifier that specifies which instance of the selected signals to export.

Specifying Data Marker Signals for Multichannel Waveform Generators

When using a waveform generator that is configured for multichannel operation, specify the channel number along with the signal identifier. For example, to export Data Marker 0 on channel 1 of a waveform generator configured for multichannel operation, use the value 1/ DataMarker0. If you do not specify a channel when using a waveform generator configured for multichannel generation, the Data Marker generates on all channels.

Default: None

signal

Signal to export.

Name Value Description
Sample Clock 101 The Sample Clock is exported.
Sample Clock Timebase 1006 The Sample Clock Timebase is exported.
Reference Clock 102 The Reference Clock is exported.
Onboard Reference Clock 1019 The onboard 10 MHz synchronization clock is exported. Only applies to PCI devices.
Start Trigger 1004 The Start Trigger is exported.
Script Trigger 103 The Script Trigger is exported.
Marker Event 1001 The Marker Event is exported.
Data Marker Event 108 The Data Marker Event is exported.
Ready For Start Event 105 The Ready For Start Event is exported.
Started Event 106 The Started Event is exported.
Done Event 107 The Done Event is exported.
Synchronization Pulse 1007 The synchronization pulse is exported. This signal is a synchronization strobe that is used to guarantee absolute synchronization between two or more waveform generators. Only applies to the PXI-5404.
Sync Out 1002 The SYNC OUT signal is exported. This signal is normally exported on the SYNC OUT front panel connector.

session out

Reference to your instrument session to wire to the next node.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.
