Intersesting.
When I use 8-bit samples with decim=8 or higher, things are peachy.
But when I use decim=16 with 8-bits samples, I get a continuous stream
of -423dB out of the FFT Log Power sink.
I think what I'm getting is a pile of 0s from the USRP when decim=4.
Can anybody confirm that decim < 8 actually works on the USRP?
OK, let's try that again with my brain actually engaged.
Anything with decim=8 or higher, in 8-bit mode, produces "sensible" samples.
Anything with decim lower than 8 (like 4) produces nonsensical results
in the Log Power FFT sink (a continuous block
of -423dB). I suspect that with decim=4, there ain't nothing but
zeros going across the USB.
So, does decim=4 actually work on the USRP, or do I need different firmware?
