[Discuss-gnuradio] min. decimation value

[Shravan Rayanchu]

Hello everyone,

My understanding is that the decimation value for the fpga has to be
between [4, 256]. In usrp_spectrum_sense.py, when I set the decimation
values to 16 or 8 (spanning 4Mhz and 8Mhz chunk at once), then
m.data[0] ...m.data[255] print out fine. However, when I set the
decimation to 4 (i.e. we will be observing a chunk of 16 Mhz), then
all the  values data[0] ..data[255] are ZERO.

I am trying to understand why is this the case .. is it that the USB
is not fast enough for decimation value of 4? I get some "u0"s printed
out even when I run for decimation values of 16 and 8 ... is this a
cause of concern?

I appreciate the help.

Thanks,

Shravan.
