Look at the samples in the scope sink. Do you see a pattern of A A B B
C C D D, meaning instead of unique samples, is every one repeated?
If so, it means that the halfband decimator is probably not being
bypassed properly.
Here are the first 100 8 bit samples from the

Matt,
How do you get 16 bits of precision from a 12 bit ADC? What does 16+
mean? I'm looking at the shorts coming from the USRP and I'm seeing
values in the range

Thank you, that's exactly what it looks like. Adding USRP pga gain
didn't help though. I'll get back to the group...

Hello,
I would like to construct a sample and hold function with :
src_data=(0,)*4095,1
delay2=gr.vector_source_b(src_data,True)
sample_and_hold = gr.sample_and_hold_ff()
I would like that that sample and hold had a duration of 4096 cycles
(4095 "0" followed by a "1").
But constructing my v
