IviRFSigGen Configure Frequency Sweep Center Span [FSW] (G Dataflow)

Last Modified: October 24, 2017

Configures the center frequency and span for a frequency sweep.

This node modifies the start and stop properties as follows:

IviRFSigGen>>Fundamental Properties>>Frequency_STEP_START = Center - Span / 2

IviRFSigGen>>Fundamental Properties>>Frequency_STEP_STOP = Center + Span / 2

span (500.0 KHz)

Specifies the frequency span for a frequency sweep. Units: Hertz Default Value: 500.0 KHz

center (50.0 MHz)

Specifies the center frequency for a frequency sweep. Units: Hertz Default Value: 50.0 MHz

instrument handle out

The instrument handle that you obtain from the IviRFSigGen Initialize Node or IviRFSigGen Initialize With Options Node. The handle identifies a particular instrument session.

Default: None

error out

Error information.

The node produces this output 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.
