Hi Marcus, Thank you for your response. Unfortunately our N300s have Rev H motherboards so version 3.12 doesn't seem to be an option for us.
Regarding our application, we have been using the E310s for our waveform application development over the past few years and recently received two new N300s to provide improved performance in network mode. We are currently working with one license for a software development tool that restricts us to network mode only due to licensing restrictions. One of our project objectives is to develop portable, hardware agnostic waveform applications so that we can conceivably use our applications on various SDR platforms. Therefore we'd like to have the flexibility to switch between both the e310 and N300 for development purposes and demonstrate software portability. Appreciate any suggestions/feedback on alternative options you may have that would allow us to use both SDRs from one host machine.
