Hi Jason,

I have been seriously considering one of their logic analyses after the
Amphour interview.  I played with the software and was disappointed to
discover they dont allow for arbitrarily slow sample rates for long term
recording.  They seem to support a range of fast sampling which would
quickly fill the HDD.  Great for capturing and decoding but not so good for
something like temperature logging.

There is obviously a reason but it is lost on me.

Cheers Justin
