Probe Compensation Signal Start (G Dataflow)

Last Modified: November 19, 2018

Generates a 1 kHz square wave signal for probe compensation.

Most oscilloscopes output the probe compensation signal on PFI 1.

connector_pane_image
datatype_icon

session in

Handle that identifies the NI-SCOPE instrument session as previously allocated by Initialize With Options.

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

session out

Reference to the NI-SCOPE instrument session to pass to the next node in the program.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Device-Specific Behavior

The following oscilloscopes output the probe compensation signal in unique locations.

Device Output Location

PXIe-5110

PXIe-5111

PXIe-5113

Probe compensation terminal
spd-note-note
Note  

The signal at this terminal is enabled by default.

PXIe-5163

PXIe-5164

SMB PFI 0
spd-note-note
Note  

Though the PFI 0 line is also available from the AUX 0 MHDMR connector of these oscilloscopes, the probe compensation signal is available only from SMB PFI 0.
