[Discuss-gnuradio] usrp2 reference clock
Hi, I'm a new comer to usrp2. If we want to use a reference 10MHz clock instead of 100MHz, is there any hardware modification needed? Now I only change the fpga_master_clock_freq in usrp2_impl.cc from *freq = 1L to *freq = 1000L. I tried to send digital signal in gnuradio-example/python/digital, but it doesn't work, the signal is still the same as before. Is there any suggestion? Thanks very much!

[Discuss-gnuradio] Tx Rate of OFDM
Hi, Could somebody tell me the maximal rate which can be acheived using OFDM in USRP currently? Is this achieved by using benchmark_ofdm_tx(rx).py? Another question is that is there any source code on MIMO+OFDM available? I noticed that USRP can support MIMO, but I didn't find any code on MIMO+OFDM. Thanks very much!
