IVI-com PowerMeter: Getting to Channel and Measurement interface and using FetchCwPower & FetchWaveform

I need a bit of help for the proper usage of the Channel and Measurement interface of IVI-COM driver. I have a sucessfully used the Active-X Automation Open, then the intiate methods via the class browser. Also know that there is communication with the device as some various properties can be set, but Im a bit stuck on the correct way to wireup and use the Measurements on Channel. In C# the syntax is myMeter.Channels.Items["CH1"].Measurements.FetchCwPower or FetchWaveform.

Pretty sure the Channels interface down Wiring down to the Channel, then passing the name in a constant, then to Measurements. But the Blue IsValid input and output wire connection are throwing me off, and causing labview to bomb. Any basic help with or example vi using IVI-COM and iviPwrMeter and the Channel Measurements would be appreciated!!

Could you please send a screenshot of your code?  Also, what device are you trying to connect to?

Are you trying to use the class driver or the instrument specific driver? For the class driver, is your IVI-COM driver listed in MAX?

For an example of using the instrument specific driver, see http://www.ni.com/white-paper/4505/en/
