Issue Details

Is it possible to address the channels of my NI-USRP using separate sessions? i.e. One session is open with RF0 TX1 and an independent session is opened with RF1 TX1:


Because of the fact that the NI-USRP driver's "Open Session" function creates a session based on the USRP's IP Address / Device Name, there is no way to open a device session specific to either RF Channel natively using the NI-USRP driver.

Additional Information

Since a large portion of the NI-USRP API takes a "channel list" input to differentiate settings and commands for different channels, it is possible to emulate a session-based framework with the USRP. However this is not functionality that is build into the driver.
