Using B200 Mini USRPs for SISO srsRAN gNB–srsUE registration

[mdhinwa]

Hello everyone,

I am planning to test srsRAN gNB and srsUE in a basic SISO(1×1) configuration. I found the following setup diagram in Ettus knowledge base-

For my use case, I would like to replace both the X410 and B210 with B200 Mini USRPs and perform only:

• Single UE registration / attach
• SISO (1×1), no MIMO
• Basic downlink and uplink connectivity
• No throughput or performance benchmarking

My questions are:

1. Is this new setup supported and known to work with srsRAN + srsUE for a basic UE registration?
2. Are there any known limitations or pitfalls when using B200 Mini for both gNB and UE?
3. Is an RF splitter necessary for this SISO case, or is a direct cabled connection with attenuation sufficient?

Any configuration tips or confirmation from others who have tested a similar setup would be greatly appreciated.

Thank you!
