[Discuss-gnuradio] Scanning whole spectrum using TVRX

2010-04-06 Thread Anand Padmanabha Iyer
Dear All, I have a TVRX board, and am trying to do some experiments with it. My requirement is to scan the entire spectrum (50MHz - 860MHz), and dump the samples for processing using MATLAB. At a time, I am sensing 250KHz of spectrum (decimation 256), and I am collecting 10,000 samples (40 ms sens

2009-12-16 Thread Anand Padmanabha Iyer
Dear All, Our research project requires the use of sub-GHz daughterboards in the USRP. We have identified the TVRX receiver board and RFX400 transceiver (is there any other option that supports the range that is supported by the TVRX on TX side?). However, our confusion is on the antenna to be use

[Discuss-gnuradio] Re: USRP2 FPGA capabilities

2009-10-08 Thread Anand Padmanabha Iyer
All, We are working on a cognitive radio project, and are contemplating on using the USRP as our platform. However, we have strict timing requirements in our MAC design. We understand that the USRP2 has a much more capable FPGA compared to USRP1. What we would like to know from the community is:
