Re: SJTP: Minutes from 08-May meeting
i agree that tests which are done with anything that
simulates a real end-use
condition will return better indication than any DC condition (i don't
have data
either, it's just a combination of logical reasoning and personal
experience).
but for this effort, isn't it also true that you must either describe a
set of common
electrical characteristics for a transmitter or describe a common set of
drive
conditions? i expect the latter is a better choice, but don't know
whether or not
the group is already working on that.
