[Discuss-gnuradio] Fluctuating gain in flex1800 ?

2008-04-22 Thread Per Zetterberg
Dear All, I am sampling a CW (1766.6MHz) using an flexrf1800. The amplitude seems to fluctuate 0.3dB (peak-to-peak). It don't think it is due to measurement noise because the SNR is high. Is this behaviour normal or am I likely doing something wrong ? Could it be the signal from the D/A

[Discuss-gnuradio] Working with the OFDM code without USRPs

2008-04-22 Thread Hoo-chang Shin
Hi, I tried to communicate between the OFDM code without the USRPs, doing: - from the 'benchmark_ofdm_tx.py' saved the output to the 'gr.file_sink', instead of giving it to 'usrp.sink_c' - from the 'benchmark_ofdm_rx.py' read from the file with 'gr.file_source', instead of receiving it from

In the output of './configure --help' are there any options regarding dll's? I think this line is what is fouling you up: checking if package supports dlls... no hth, Jason. No, I didn't see any option concerning dll, options available are: $ ./configure --help Usage:

[Discuss-gnuradio]usrp_sounder question

2008-04-22 Thread Qi Chen
Hi all, I have a question about the usrp_sounder. I realized that it uses a custom fpga bit file to avoid the USB I/O bottleneck entirely, which makes sense to me. So if I would like to do off-line processing (cross-correlation, and etc) instead of real-time, I would use usrp_rx_cfile.py
