Question on GPSDO #94

Hello,

Instructions say to:

Using 2 USRP B-Series. LTESniffer utilizes 2 USRP B-series (B210/B200) for uplink and downlink separately. It achieves synchronization between 2 USRPs by using GPSDO for clock source and time reference. GPSDO is mandatory for this option. To use this option, please refer to the LTESniffer-multi-usrp branch of LTESniffer and its README.

I was wondering if there was a specific GPSDO you used or would recommend to get two USRP b200s to work. Thank you.
