Can we use any sampling rate in tunnel.py or benchmark_tx.py

Hi friends,

This question may sound stupid but I cannot really know if I am thinking
right or wrong.

Can I set the sampling rate of tunnel or benchmark_tx to be anything (of
course to those supported by the system) as I think as far as the data
rate
of USB is maintained I should be able to do that. Isn’t it?

If yes, then can I just use the “-S samplingrate” option while running
the
program or is there anything more that I need to consider.

Thanks,
Ali

benchmark_*.py files use an included set of functions called
‘pick_bitrate’ that will attempt to automatically decide correct
parameters given the ones you specify. If you tell it to use a
certain number of samples per symbol it will automatically attempt to
adjust the other parameters (mainly interpolation/decimation) to make
it work.

Please see pick_bitrate.py in the same folder for more information.
