Initiates a measurement on all enabled channels.
When this node executes, the power meter leaves the Idle state and takes a measurement on all enabled channels. Use IviPwrMeter Fetch or IviPwrMeter Fetch Channel [CH] to obtain the result of the measurements.
This node does not check the instrument status. Typically, you call this node only in a sequence of calls to other low-level driver nodes. The sequence performs one operation. You use the low-level nodes to optimize one or more aspects of interaction with the instrument. If you want to check the instrument status, call IviPwrMeter Error-Query at the conclusion of the sequence.
This node performs interchangeability checking when the IviPwrMeter>>Inherent IVI Settings>>User Options>>Interchange Check property is set to TRUE. You may use the NI I/O Trace utility to view interchangeability warnings. Alternatively, you may use IviPwrMeter Get Next Interchange Warning to retrieve interchangeability warnings. For information on interchangeability checking, refer to the online help manual.
Instrument handle that you obtain from IviPwrMeter Initialize or IviPwrMeter Initialize With Options. The handle identifies a particular instrument session.
Default: None
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.
Default: No error
