I have implemented a simple CW radar for doppler measurements using usrp x300 and echotimer. While running it the QT GUI waterfall graph is giving desired results, but the logged file using file sink, when replayed contains periodic high power spikes. Tried with unbuffered on or off both in file sink block, changing the input of file sink to echotimer output, running same flowgraph with N200 usrp, reading the file in matlab but the same result. the Picture of logged file read back and actual runtime QT GUI waterfall graph is attached below.(sorry was having some issue with taking screenshots)
thanks in advance
