measuring with both channels of virtual bench simultaneously in labview, error 375903

[NGKai]

Hi, I am trying to perform two measurements simultanously using both channels of the Virtual Bench's analog input. I have selected MSO channel 1 and 2 for the measurements yet I am getting error 375903 returned evewry time saying the resource requested is reserved. I am not running any other software that should be using the virtual bench. The error occurs when I am initializing the session, before a measurement has even been made. Can someone tell me how to call each channel so that I am not getting this resource reservation conflict?

I have included the VI and a screenshot of the error.

Thanks!

The MSO only supports a single instrument session, and your VI uses two. To use both channels, remove the second MSO session and specify both channels in the MSO Configure Analog Channel.vi

Here is an example that uses both scope channels:
