Hi Everyone I am attempting to use two B200 minis at the same time to measure differences in amplitude and phase from a single signal over coax cable and a 3dB splitter. I am using gnu radio companion to run this radio setup. I am splitting a PPS signal and running to both radios.
I am having issues in the measured phase difference. It seems that either radio is not locking to the reference (PPS), and the phase for the measured signal continues to vary as a function of time. I have attempted the following: . Use a 10MHz reference from my signal generator . Running gnu radio as admin . Issue a state timer using various delay, trigger, cycle time settings . Using various sample rates and Rx IBW Also, using a simulated source in gnu radio does produce the expected result. However, when I switch back to the radios the results are variable again. I'm beginning to think there might be an issue with the radios but would like to open a discussion to see what else we can try to get this setup going... Thanks, Bob
