Dear all,

I am planning to purchase a gpsdo kit from ettus research to set up a 2X2 mimo system using 4 usrp2s. I need your help in answering a few questions that i have.

is the gpsdo kit only meant fro the usrpN series devices only? or can they be used with usrp2 also?

in order to sync 2 Tx and 2 Rx receivers, can the clock out and pps out be split to feed these  usrps?

thanks in advance


Thanks

The GPSDO Ettus supplies is really intended to be used "in skin" in N2XX or E1XX-series devices.

However, if you supply proper power to it via an external power supply it could be used stand-alone, and the outputs split to multiple devices, although you may need to use an active splitter.
