IviACPwr Query Frequency Ramp Busy [FR] (G Dataflow)

Last Modified: October 23, 2017

Returns whether or not a frequency ramp is in progress. Call this node after calling IviACPwr Ramp Frequency [FR] to determine when the ramp completes.

instrument handle

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

Default: None

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

instrument handle out

The instrument handle that you obtain from IviACPwr Initialize or IviACPwr Initialize With Options.

error out

Error information.

The node produces this output according to standard error behavior.
