Others in my company have used the Ant8 and been happy with it.
Personally I've never used it but I own the analyzer sold at
http://www.pctestinstruments.com (under $400, barely) and am pretty happy with
it. This one also is only supported under Windows though. They do let
you download their software to check it out; if the LA isn't attached to
the system it offers to run in test mode, which includes simulation of
live incoming data so you can play with triggers, etc. The analyzer is
32 channels plus two clock inputs, samples at up to 500MHz, allows
triggers to be based on any and all signals... And one thing I haven't
played with yet: though the buffer is small (2k samples, same as the
Ant16), it supports buffer compression so it's able to store more than
2k samples if the data compresses well.
One thing to be aware of -- you need to order your clips and signal
wires seperately. What's nice though, the signal wires they sell
terminate as female connectors that can plug onto a replacable clip or
plug onto a pin header, test point, etc. It seeems the Any8 clips
terminate to permanently attached grabbers, which aren't always ideal.
I would suggest you download the LogicPort software from the link I gave
and run it in demo mode before you make a decision.

Subject: [Gumstix-users] Which Logic Analyzer
Hi all! I know this isn't logic-analyzer-users@...,
but I figured if anyone would be able to give me a great answer to this
question it would be you. Feel free to ignore me for being off topic if
you like :)
I'm looking to purchase a decent logic analyzer. I need to do some
reverse engineering of a car stereo control protocol and I don't think
my scope is going to cut it. I need to analyze at least 4 lines at once
and my scope only handles 2.
So, I'm not looking to spend a giant pile of money but I'd like
something that will be useful for a long time. I've been eyeing the Ant8
from Rocky Logic ( http://www.rockylogic.com/ ) for a while now. It fits
the cheap bill, has 8 channels and samples at 500MHz, which should be
plenty for my needs. Downside is it's PC/Windows based and I generally
work on a Mac.
So, any suggestions for a decent either self contained or Mac friendly
logic analyzer? I'd like to keep the cost under about $400.
Thanks a ton,
Jason von Nieda
