[USRP-users] E320 POE+ Adapter Suggestions

2020-01-28 Thread Kyle A Logue via USRP-users
I'm interested in using a E320 via POE+ to deliver 12v power. Does anyone have suggestions for injectors/adapters to use in combination with the E320? POE+ is supposed to be able to deliver up to 30W, which is conveniently how the E320 is 12V rated. I found one an Amazon that will do 24W (SMAKN®

Hi Austin, >Is there a way to do it directly via the jtag and using the screen command to speak with the N310? You could connect to the ARM via JTAG as detailed in the link below, but you're better off just SSH'ing into it. https://kb.ettus.com/USRP_N300/N310/N320/N321_Getting_Started_Guide#Conn

Let’s do some quick math, shall we? 5msps with 16-bit complex == 160Mbit/second 1.25msps with 16-bit complex samples == an additional 40mbit-second Unless you have super reliable 1Gig wireless infrastructure, this just isn’t going to work. Sent from my iPhone > On Jan 28, 2020, at 6:23 PM, A

Hi everyone, I have a very basic GNU script with just a USRP block and a time sink that when I run, there are tons of streaming errors with the tx and rx. In GNU, the console is being filled with 'D's and the console for the N210 is getting filled with 'U's and 'S's. My setup is just a USRP N210 c

Hello, I have an application that schedules transmissions/receives on a short time scale (order of tens of microseconds). I'm attempting to gauge the feasibility of using a x310 with UBX-160 daughterboards and 10Gb ethernet for the application. I wrote a quick test to see approximately how l

Hi Sammy, >Can I turn it off and come back the next day and still have the same phase offset between the channels that I had the day before? Yes. This assumes that you are running with the same frequency, gain, sample rate and system temperature that your calibrations were made with. Also unless
