Hi,
I am trying to replicate the following open source research project which uses an X310 with two UBX 160 daughterboards –
https://github.com/SysSec-KAIST/LTESniffer
However I only have an X410 at my disposal. The specific reasoning for the two daughterboards in this project are twofold:
1. sniffing the uplink traffic requires precise time synchronization between uplink and downlink subframes, which can be simply achieved by using two daughterboards with the same clock source from a single motherboard of USRP X310
2. the "srsran_rf_set_rx_freq" function used by LTESniffer seems to only support the USRP X310 with 2 daughterboards for simultaneous reception of signals at two different frequencies.
From what I can tell the X410 includes two 'ZBX daughterboards' (https://files.ettus.com/manual/page_zbx.html) however it's unclear to me whether these are equivalent for this application?
Any advice, tips, experiences etc very much appreciated.
