Hi, I have a USRP Rev 4.5 and I was trying to find stability information on the 64 Mhz crystal oscillator. However, I am unable to cross-reference it to a manufacturer's part number. The part number on the BOM says X2 is a digikey CTX286LVCT-ND. However the part populated on the USRP is from

[Discuss-gnuradio] script suffix deletion - tales of woe

2007-10-19 Thread L. Van Warren
In my experience in porting many systems to many platforms, suffix visibility is an essential aid to clarity and understanding. I would hope that the .py suffix would be retained, as well as all other relevant suffixes. Do what you think is best however. The workaround I will use if suffixes are

[Discuss-gnuradio] benchmark_ofdm_rx not working

2007-10-19 Thread Archana Ragothaman
Hello, I am using two USRPs rev 4 and two RFX2400. I am basically trying to make the USRPs communicate with each other using the benchmark_ofdm_tx.py and benchmark_ofdm_rx.py scripts. The commands I am executing are ./benchmark_ofdm_tx.py -f2.4e9 -T A (at one USRP connected to laptop) ./benchmar

Hi Dominik, It would be great if you could port the ofdm transceiver that you have implemented to packet_utils. I am actually using two USRPs rev4 with RFX2400 and trying to make them communicate with each other on air using ofdm. Presently I am thinking of how to synchronize the transmitter and t

[Discuss-gnuradio] Has Anyone Used Purify with GNU Radio?

2007-10-19 Thread Jeremy Chew
Hi, I am trying debug my Python MAC extension with Purify but find that the binary instrumented with Purify does not seem to transmit any packets through GNU Radio 3.0.3. I trace the transmit packets through to mod_pkts. Beyond that, I think the packets should be handled by the GNU Radio .so file
