Re: [Discuss-gnuradio] Max temperature for usrp2

If you can stand the temperature, your usrp should be fine. Matt The only additional remark I'll make is that higher temperatures do a couple of things in the analog section of any receiver: o The LNA gain will be somewhat lower (perhaps as much as 0.2dB or so) o The LNA noise tem

ow in July. Will the USRP2 be able to operate under these high temperatures? Check it out: http://www.wund.com/US/AZ/Yuma.html --- On Thu, 6/30/11, Feng Andrew Ge wrote: > From: Feng Andrew Ge > Subject: Re: [Discuss-gnuradio] Max temperature for usrp2 > To: emat...@nd.edu, discuss-gn

Eric, in your 2009 experiment indicated below, did the USRP2 sustain the high temperature of 150 F? Is there anybody else who has tried to use USRP2 continuously at a temperature above 105 F? Your feedback is highly appreciated. Andrew On Mon, Jul 13, 2009 at 1:13 PM, Eric Matlis wrote:

Why not just run some hefty cable from the test environment to the USRP? Sounds fun, though! Jordan On Mon, Jul 13, 2009 at 1:13 PM, Eric Matlis wrote: > Hi all- > > I'm about to conduct some measurements on a running GE aircraft jet engine > with the USRP2. The test cell temps could reach 150
