Dale,

Glad you are happy with the AA-200 but the ability to calibrate an
analyzer with standards at the end of a cable or through a filter is
IMHO the absolute most important feature an analyzer can have. The
difference in accuracy is huge. Additionally the ability to make
measurements with a tuned tracking receiver rather than a broadband
detector separates the toys from the real equipment in the presence of
other RF interference when making antenna measurements. Granted that
the absence of a PC is a plus but the larger screen of a notebook PC is
a big deal to me as is the ability to capture plots for others to see.
I would take the AIM4170 over the AA-200 any day. If you wish, take a
look at http://www.bnk.com/w0qe/AIM4170_page1.html for a detailed
examination of the AIM4170. I am in no way connected to Array Solutions
who sells the 4170.

I'll second that Larry. If you really want to soar add a Bluetooth to
RS232 serial adapter and battery to the AIM. That makes it much more
convenient to use plus it will improve measurement accuracies by
easily having everything floating above ground potential.
