[Discuss-gnuradio] USRP heating up !

2005-04-05 Thread Javs
Dear all,   The Analog Device chips on my USRP (and to some extent the FPGA) seem to be heating more than usual now. On a touch basis, I observed that they are much heated (burning sensation) than they were before. I've been using it for about 40 days now. I haven't done anything unusual with it.

Hi, guys I met some confusions when I tried the usrp_fft and usrp_oscope. I generate a 2MHz, peak to peak 1V, sin wave using the Agilent signal generator, and connect it to usrp. However, the result of usrp_fft always shows a very strong component at DC, besides the 2MHz. Why is that? Then I tr

[Discuss-gnuradio] USRP and DC offset

2005-04-05 Thread Matt Ettus
A lot of questions about DC offset have come up lately, so I just wanted to clear things up a bit. The discussion applies to both TX and RX, but I will speak in terms of the RX. The USRP has 2 kinds of DC offset. The first is "real" DC offset. All AD converters have some natural DC offset to

Hi - I have an Avnet Virtex 4 evaluation board, intended for projects similar in concept to GNU Radio. It uses the same CY7C68013 chip as USRP. I used USRP as a software reference design, and started splicing in some code of my own. I think that part is in good shape, after coming up to speed o

Are you physically plugged into a USB 2.0 port? A system may have multiple of USB ports, but not all of them are 2.0. Many will be USB 1.1 (high-speed 12mbps) devices. If you run usbtree, you can verify your connection. The following is an example of the USRP connected to an USB 2.0 port. [E
