Re: [Discuss-gnuradio] Resolution of USRP N210 and N200

To add to what Ben has wrote, if decimation is involved in the processing stages it is possible to get a higher resolution than that of the initial samples. For example, a decimation by a factor of two can increase the bit precision by one. So in this case, it could depend on where the interface is

Hi Ting - Sorry, there really wasn't a good reason for me to not answer your question, regardless =) So the ADCs are indeed 14 bits, but those samples go through a lot of processing on a number of different platforms, and get sent over a few different buses. At any of these stages, depending on y

Ting - This question really isn't GNURadio related. If you resend it over the USRP-Users list, though, we will help explain things quickly! http://lists.ettus.com/mailman/listinfo/usrp-users_lists.ettus.com Cheers, Ben On Sat, Nov 2, 2013 at 12:22 AM, Ting Wu < wu.t...@comf5.comm.eng.osaka-u.a

[Discuss-gnuradio] Resolution of USRP N210 and N200

2013-11-02 Thread Ting Wu
Hi, Both of USRP N210 and N200 have 14 bit ADC, which means a range of +/-2e13=+/-8129. However, as I tested a N210 with LFRX, I got values from -32704 ~ 30073, close to +/-2e15=32768. Last year, I also tested a N200 with LFRX, I got values from -16357 ~ 16241, close to +/-2e14=16384. The sa
