Okay, that figures. Prices on Ebay are a bit higher.

The is an all analog scope (at least the measurement part) and its not made by Lecroy. Its the first one on this page:

Ok, but that ain't LeCroy. Thanks for the link though, have bookmarked it because there will come a point where I am still recommending Tek
2465 scopes to clients but the supply will have shriveled up. They (unfortunatly) don't make'em like they used to.-- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam. Use another domain or send PM.

About us$ 8000 new, probes extra it seems. Nor have i ever heard any reason to seriously doubt Iwatsu spec's.

Target the CATV and telephone installer markets. Something they can use with a laptop should sell
What would be nice is a four channel TDR to test ethernet cabling. That would show proper wiring pattern and cable condition. Four differential outputs to test the twisted pairs, and a 4*2 input mux to select each pair in turn. The ability to drive each pair separately would allow testing for crosstalk, as well.
The ability to save or print the data on an installation would make it a lot easier to troubleshoot, later on.

AFAIK Iwatsu has a good reputation. But a Tek 2465 from Ebay would only be around $500, plus possibly a new round of knobs for another $100 or so, plus a couple hours of sweat equity. The delay-trigger shifter on those things is kind of wimpy and its plastic gets brittle. Almost the best analog scopes since sliced bread but on the mechanics they could have done better.

Ideally, it shouldn't need the laptop to do the check. It should charge its self from the USB.
It should have a "cable active" light on it.
There is enough POE systems to make a DC voltage measurement a good idea.
It should be defended against mains voltage on the wires. I say this from sad experience with an RS-232 cable and a chassis that got hot somehow.

That certainly is what they get used for at 5 to 30 GHz.
Idally, you should know something about the application. Using a TDR with logging would make troubkleshooting much eaiser. If you can store all the details of several hundred miles of coax in a self contained, USB charged device the market is waiting.
There is 60 volt AC modified sinewave on a lot of CATV coax.
Like I said above, you need to know the market.
