Hi guys, I'm trying to generate complex I/Q waveforms using this command (for 700 KHz):
./usrp_siggen.py -T A -w 700000 -f 0 >From the mailing list, I've read that the USRP can transmit up to 44 MHz. Unfortunately I can only transmit clean quadrature I/Q signal only up to 700 kHz. Above the frequency, I'm starting to see two or more waveforms for each generated quadrature I/Q signals. If I increase the frequency further to 1 MHz, USRP only generate one signal from TX_A connector, there is no signal from TX_B connector. Both TX_A and TX_B connectors are on daughter board of 'USRP Tx side A' as indicated by '-T' flag. FYI, I'm using LFTX daughter board not the Basic ones. If I transmit more than 1 MHz, the frequency is still cap at 1 MHz. Any idea what is happening and how to get higher frequency? Thanks, Regards, Shaiful __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
