It's probably true to say that Eagle will use 20,000 transistors to do the same job as 20 transistors in Oscar 7. But it's also fair to say those 20,000 transistors will do a much better job.
....hmmm, and its also unfair to don't say that, the possibility for a malfuction with 20,000 vs 20 transistors is .... 1,000 times greater !
Simple mathematics... even if these 20,000 transistors do a better job, the risk is too big.
Even simpler math ... 1 out of 20 failing is likely worse than 1 out of 20,000 ...
G0MRF is correct of course ... SuitSat-2 will test the SDX ...
I'm not sure where anyone thinks this "debate" is going - it IS going to be an SDX and not analog ... this has already been decided on as far as I can see ... and I sat through a lot of talks at the DCC about this stuff. Because that is: a) what the guys doing all of the work want to do, and b) what is required to provide the services desired for the power budget available.
However, we might be able to put a spark-gap up there if we need something "rad-hardened" ...
