[time-nuts] is there a cheap and simple way to measure OCXOs?

[Ulrich Bangert]

Attila,

concerning the mixer this is not the best choice. Consider to buy a
dedicated phase detector as shown in

http://217.34.103.131/products/PhaseDetectors.shtml

which gives you higher and almost phase linear output at an increased output
level. You need 7 dBm at both input ports.

Best regards
Ulrich
