Hello All,
As I have stated in the past Im interested in VNA style measurements. Specifically S21. From what I have read and found out experimentally I need two coherent recievers to do this. And thus I need MIMO or something MIMO like.
Scenario 1 - Two USRP2 systems connected by a MIMO cable:
Scenario 2 - Up to Four USRP2 systems connected by MIMO cables to the not-yet-in-existence HUB:
Scenario 3 - An arbitrary number of USRP2 systems, no MIMO cables, no HUB:
Now it looks like MIMO is available or Scenario 1. But it requires the UHD driver and an updated GRC version. Is this correct? How do I differentiate between whether I have this functionality or not? Is there a way to query the USRP and find this? I didn't build GRC myself. I have v3.3.1git-47-gf6337c62. Is this the right version?
Thanks,
Justin.
