Hi list,
I want to use 4 bit sample to enlarge my signal bandwidth, however my
program can not
work with 4 bit sample, and I trace into fpga code also can not find
anything related to
4 bit sample however there is 8 bit sample and 16 bit sample code. So I need
to be confirmed
is 4 bit supported in current fpga code?
Regards!

No, only 32-bit samples (16 bits I, 16 bits Q)

Hi Josh,
Are there any plans to support and implement 4 bit in future?
Regards,
Thomas

Well, there is a plan to do 16 bit samples (8-I, 8-Q). I suppose it
wouldnt be such a leap to work in 8 bit samples at the same time.
What did everybody mean by 4 bits per sample? 1 byte per complex sample
(4-I, 4-Q)? I can't imagine doing sub-byte samples.

Hi,
I was thought about 4 bit (4-I, 4-Q) just because it shuld allow the
full 50 Msps in dual USRP (MIMO) single Ethernet configuration.
Well, there is a plan to do 16 bit samples (8-I, 8-Q). I suppose it
wouldnt be such a leap to work in 8 bit samples at the same time.
That would also be great. For my applications dynamic range is less
critical than bandwidth.

Yeah I mean (4-I, 4-Q), there is already support (8-I, 8-Q) in current
version.
