[Discuss-gnuradio] Inexpensive Digital RF Signal Generator

2019-06-26 Thread cliff palmer
I'd like to buy/build an inexpensive digital RF signal generator for testing RF scan/capture projects. I want something that - generates a digital pattern I specify (512 - 32k bits) - on a frequency I select (somewhere in the 100M - 500M range but the range of frequencies can be much narrower) - i

Hi Michael, We have implemented one channel OFDM using rational resampler and pfb synthesizer and multiply tag block. It's working and we can receiver packets over the air. Thanks for suggestions. We have also tried to implement two channels. We have resampled OFDM signals to 500KHz using ra

Hi Ramazan - The "tP" means that a timed transmit came too early. Say you want to transmit exactly every second (via timed samples), but you provided UHD with a burst of 2 seconds of data. You will have a new timed command before the first burst is finished. Hence, UHD will print "tP". I'm guess
