[Discuss-gnuradio] hi all, can I use one RX receive a wideband signal and then seperate it to many narrowband signals

2010-12-21 Thread James Jordan
Hi all, I need to receive many narrowband signals, but usrp hard ware only provide 4 RX, so I need to receive more than one narrowband signals per RX. Is my idea possible? I dont want to use more than one usrp to achieve that, anyway which will be an option if my first idea can't work.

Hi all, I am checking my usrp setup with benchmark_tx and benchmark_rx scripts. The results I got were very odd, I want to ask your opinion about it. HW setup: I have two "nodes" and each node has 1x laptop, 1x USRP1 with 2x RFX2400 daughter cards. The two RX/TX ports from a node are connected

If the ethtool output you provided is with the USRP2 plugged in and turned on, then your ethernet card isn't detecting a link. If another computer works fine with that same USRP2, I suspect the ethernet cable or your ethernet card as the culprit. You might also try: sudo ifconfig eth0 up and see

Short answer: you can go as wide as your CPU will handle. If you only need a few channels but they're separated by a few MHz, use the frequency xlating filters to bring each channel to baseband. If you have a regularly-spaced band, use the channelizer. --n On Tue, 2010-12-21 at 14:10 -0500, Walk
