USB Logic Analyzers
Archiver
Posts: 46,084
Funny you should ask.
I've recently invested some bucks in checking out
what's available in USB based Logic Analyzers.
The two I chose to check out (based on price)
were the USBEE LX and the Ant8 (an Ant16 soon avail).
The Ant8 is www.rockylogic.com ($218 with probes).
This is based on the FTDI USB chipset
http://www.ftdichip.com/FTD2XXDriver.htm
This is a 500 MHz to 100 hz 8-bit logic analyzer.
It is spec'ed at +- 40Volt input.
I highly recommend this one, though my 'old'
win98 Toshiba 26xx laptop won't work with it.
(The OS hangs while trying to talk to it)
It has a very nice user interface, lets you
'free run' your analyzer, has very nice
triggering logic, and has a nice way of showing
the signals before and after the trigger.
The USBee is also very nice(www.cwav.com)
(LX unit $445, Std unit $295)
This unit is based on the Cypress EZ-USB
architecture. It supports 24 MHZ to 1Khz
sample rates. This unit has a LOT of
flexibility, just by selecting different
free applications which come with it,
this unit acts as a (one at a time):
1. Logic Analyzer
2. 8-bit 24 MHZ signal generator
3. 1 (LX) or 2 channel frequency counter (0..6 MHz)
4. Datalogger
5. PC Keyboard to Logic Pin generator.
6. Has a VB or VC++ programming interface, so
you can automate logic capture or signal
generation.
The user interface is very similar to the
Ant8. The triggering options are simpler.
This one works fine with my Toshiba.
For 'plain' logic analyzer use, I prefer the
Ant8 (price and higher sample rate). For
flexibility and programming I like the USBee.
I just looked at their site, and it looks like
they have a new 'EX' model -- don't know about
it.
Hope this helps. AllanL.
