[Discuss-gnuradio] REF clock for USRP2

[Feng Andrew Ge]

Would  experienced users please recommend me a 10MHz REF clock for stabilizing USRP2? I followed previous emails and found that "any 10 MHz reference (square or sine wave, DC-blocked and terminated in 50 ohms, 3V pk-pk) with  will suffice, it does not need to be a pulse per second source." As such, is there any existing product that I can purchase directly.
A REF clock without GPSDO will be excellent.

Than you in advance,
Andrew
