I am working on project that I need to use a USRP2,but when I try to calibrate it,I get the above error(on attached graph) or" time out waiting for TX and/or RX LO to lock".Anyone here knows how to get a rid of this?
Thank you
Tough to say the reason, it could be a number of possibilities.
Heres some questions/stuff you can try:
1) Which LO is failing to lock RX or TX? The logic is in the
tune_rx_and_tx() routine of the .cpp file.
2) Perhaps the timeout is marginal. Does increasing the timeout allow
for lock?
3) Perhaps locking at lower frequencies is marginal. Does increasing the
start frequency --freq_start allow for lock across all frequencies in range?
4) Perhaps there is a hw issue? Does the board work as expected with
simple test tones, transmit and receive. Do you have another device to
cross reference?
best regards
you may attached excel sheet for the plotting of your graph, where your output is coming.
1. Add a excel sheet that extract the data
2. plot using office
