Hello,

I am using gnuradio and a usrp2 to capture samples (shorts) to a file,

that is 16 bit I and 16 bit Q.

I looked at this data in matlab and noticed that in many instances the

samples exceed 13 and 14 bits

for both positive and negative numbers (ie -12567 or +12989).

I was under the impression that a 14 bit a/d meant 13 bits plus a sign

bit so max 8191, min -8191.

Should I expect this behavior, am I interpreting something incorrectly.

If this is expected

can someone please explain. I though the rx_gain was applied before the

a/d so the max

output would be be 13 bits plus a sign bit.

Thank you,

Sharif
