IviRFSigGen Reset Interchange Check (G Dataflow)

Last Modified: October 23, 2017

Determines if each test module completely configures the state of each instrument it uses. By calling this node at the beginning of a test module, you can determine whether the test module has dependencies on the operation of previously executed test modules. After you call this node, the interchangeability checking algorithms in the specific driver ignore all previous configuration operations.

connector_pane_image
datatype_icon

instrument handle

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

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

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

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Test Systems with Multiple Test Modules

When developing a complex test system that consists of multiple test modules, it is generally a good idea to design the test modules so that they can run in any order. To do so requires ensuring that each test module completely configures the state of each instrument it uses. If a particular test module does not completely configure the state of an instrument, the state of the instrument depends on the configuration from a previously executed test module. If you execute the test modules in a different order, the behavior of the instrument and therefore the entire test module is likely to change. This change in behavior is generally instrument specific and represents an interchangeability problem.

Clearing Interchangeability Warnings

If you want to guarantee that IviRFSigGen Get Next Interchange Warning only returns those interchangeability warnings that are generated after calling this node, you must clear the list of interchangeability warnings. You can clear the interchangeability warnings list by repeatedly calling IviRFSigGen Get Next Interchange Warning until no more interchangeability warnings are returned. If you are not interested in the content of those warnings, you can call IviRFSigGen Clear Interchange Warnings.
