Question regarding the over-air SRSRAN setup

[wmwwimor]

Equipment:

• A host with Ubuntu installed
• One X310 using PCIe connected

I want to set up an over-air network with srsUE, gNB, and 5GC. I have two possible approaches, and I'd like to know if either of them is feasible:

1. The X310 itself has two transceiver ports. I'm not sure if a single X310 can serve both as UE and gNB. If I attach two sets of antennas, would that work? If it's possible, how should I differentiate between the two sets of ports? In this case, can both sets of ports share the internal clock（I don't have GPSDO in X310）?

2. If I use one X310 to serve only as UE or gNB, will I still be able to set up the system? I noticed that the official tutorial recommends connecting the host via the Ethernet port in CU/DU format, so is using PCIe not feasible for this?
