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

This question really isn't GNURadio related. If you resend it over the
USRP-Users list, though, we will help explain things quickly!

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.
