# Symbol Map (G Dataflow)

Version:

Configures the symbol map that you use during measurements.

## Session In

Session In specifies the RFmx session refnum. Session In is obtained from the RFmxInstr Initialize NIRFSA node.

## Symbol Map Type

Symbol Map Type specifies whether the measurement uses the default symbol map or the map that you configure using the RFmxDemod DDemod Configure Symbol Map node.

Name Value Description
Auto 0

Uses a default symbol map.

Custom 1

Uses the map that you specify.

## Symbol Map

Symbol Map specifies the custom symbol map.

## Selector String

Selector String comprises of the signal name. If you do not specify the signal name, the default signal instance is used.

Example:

""

"signal::sig1"

You can use the Build Signal String node to build the selector string.

Default: "" (empty string)

## 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.

## Session Out

Session Out passes a reference to your RFmx session to the next node.

## error out

Error information.

The node produces this output according to standard error behavior.
