Query on USRP MIMO synchronization using GPSDO

GNU Radio
1

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
Regards

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.
