I am looking for a differential amplifer and probes. I know that
Lecroy sells a fine machine (used to be preamble) for a few thousand.
Very fast and has a very good cmrr if probes set up just so.

I need to look at alternate vendors to keep Lecroy honest.

any suggestions?


While we are on the test gear subject - are there any vendors which
produce a similar current probe and amplifier setup as the Tektronix
A6302? I'm looking at the Lecroy plug-in probe as a replacement for
the Tek solution I've been using for so long. Again, I'd like to know
if any high performance alternatives exist. I happened to catch one of
the chimpanzees from production with my Tek probe last week and I've
got to put a stop to this nonsense right away!

Any suggestions?

regards,
Bob

TEK still makes accessory differential probes.

TEGAM had acquired the TEK TM500 line including the A6302/AM503/TM501
current probe and amp.I do not know if they still make them,I recall
hearing that they have stopped. www.tegam.com

Look for Tektronix and HP. Nice probes, but of course same price range.

Don't worry. Lecroy knows what they can get - for a time they had an
OEM HP differntiel probe in their catalogue. I guess this says it.

Not with this current/frequency-range combintion. If you are willing to
suffer on frequency range: HP, Fluke, LEM, etc. will have similar
styled products.

You are taking about a CURRENT probe? Well, the tek is still unbeaten
for the price/performance ratio.

none I am aware of ;-)

Well, interesting to note that the chimpanzees can be trained to work
in production :))
Any suggestions?

1.) employ better trained personal.
2.) buy more probes (== spend more money)
3.) buy tektronix.
4.) do as Jim yanik suggested: Tegam and 2nd hand market of PLENTY of
these units for a reasonable price (reasonable if you are a
professional, but these probes are no amateur stuff anyway).

hth,
Andreas
