[USRP-users] Spikes at beginning and end of transmission

2018-02-24 Thread Thomas Teisberg via USRP-users
I'm working on a radar project that requires sending a series of short pulses. Looking at the pulses on a scope, I'm seeing large voltage spikes at the beginning and the end of each transmission. As shown in the attached screenshot, before the transmission starts, there is a 90 mV spike lasting ab

Hello Evan: I think that you need to have a license for the Communication Toolbox in order to use the USRP Support Package for Matlab, but I would contact technical support at The MathWorks to confirm this. https://www.mathworks.com/hardware-support/usrp.html There is nothing that you need from

Hi Jason, this just means that the loader can't even open the file you specified. It looks like you're missing the leading "/" of the absolute path you're specifying. Best regards, Marcus On Fri, 2018-02-23 at 13:46 -0500, Jason Meyer via USRP-users wrote: > Hi, > > I am trying to build a cust

Hi Evan, you simply install the USRP Hardware Support Package (as you did), and then you are displayed this license agreement which applies to you automatically. You are now able to use USRPs with Matlab! There's no further steps you need to take. Best regards, Marcus On Sat, 2018-02-24 at 17:39
