hi, I was just wondering whether the USRP has got some temperature specs that i should take into account. e.g. maximum continuous usage time, need for cooling, possibility to be enclosed in a case or anything else. ...just because I noticed that during long testing sessions (2 to 4 hours) the FPGA and the TVRX warm up quite a bit. thanks vincenzo

At room temperature the USRP can run all-out continuously for days at a time. Any enclosure should take the power consumption of the system into account. This can be as high as 15-18 Watts depending on what daughterboards you use. An enclosure for the USRP will be released some time in the next 2 months. Matt

With a room temperature near 20C, it runs at about 38C. I run the USRP+DBS_RX more-or-less continuously for radio astronomy applications. In my application tiny temperature-induced gain variations can be a real problem, hence the need to stabilize the temperature.
