[Discuss-gnuradio] problem with over-the-wire format sc8

[Andrej Tissen]

Hi List,

i wanted to try out the over-the-wire sc8.

For this i use the utility "rx_sample_to_file".

By sc8 i see a problem in time and frequency domain.

In time domain and with --wirefmt sc8 i get only "-256,0,256" values (i use: --type short)

Is it possible to use sc8 with this utility "rx_sample_to_file"? What is wrong??

I attached two pictures of the over-the-wire sc8 and sc16…

for sc16 i receive the data with: 

./rx_samples_to_file --wirefmt sc16 --freq 658000000 --gain 29 --rate 25000000 --nsamps 51200

and for sc8 i receive the date with:

./rx_samples_to_file --wirefmt sc8 --freq 658000000 --gain 29 --rate 25000000 --nsamps 51200

UHD-version:

linux; GNU C++ version 4.4.3; Boost_104000; UHD_003.004.000-19-g74a9352c

many thanks in advance
