Re: [Discuss-gnuradio] Running tunnel.py/benchmark_tx.py (OFDM) with XCVR2450?

That's kinda odd now that I think about it, I had a similar problem and on an oscilloscope it looked like DAC clipping, but I could have been non-linearity in the final amp, what kind of problems do XCVR2450 have at high outputs?

I'm thinking that too, there
really should be some kind of warning when you drive the DAC to
It's not the DAC that's typically the problem, it's the final RF
amplifier on the daughter-card, and
that's not precisely predictable from the software side.
