Default USB Curve Tracer

I've been looking to buy a curve tracer for a while, but up to now they've all been very expensive.
However Circuit-Ed produced a USB version which looked like it would fit the bill:
Circuit-Ed - Electronic Development Products
When I tried to buy one it said they were no longer available. I emailed them for info but - no reply.
One of the guy's here said that Circuit-Ed were working on a new version (?)

I've noticed that Elektor have produced a kit for a USB Curve Tracer:
Transistor Curve Tracer - ELEKTOR.com | Electronics: Microcontrollers Embedded Audio Digital Analogue Test Measurement
Again, this looks like it might be just the thing.
Anybody here checked this out ?

I havn't tried this myself, but there is some useful feedback in the elektor forums from those who have here.

Seems that a little perserverence is required

Thanks for that Mike. That's why this forum is great!
You wouldn't find that kind of info so easily anywhere else.

I'm glad I didn't buy the Elektor thing. If there's one thing I don't need it's test equipment that needs testing!

But I'll keep looking - I really would like a decent curve tracer.
Maybe Circuit-Ed will eventually prodjuce an updated version.

Thanks again.

A USB curve tracer would be really sweet.

I was hoping that wds would post something about this (I believe he was involved with the design).
Also ilardi said that Circuit-Ed were working on a CT-200 - but, no news on that either.

Stefano.
Maybe you could ask them about the CT-200 which Circuit-Ed said they were working on.
It's supposed to be an improved version of the CT-100 which, as you said, they don't make anymore.
It would be nice to know if they are going to go ahead with it.
I would really like one!

no they are not going to.
They said they don't have any curve tracer on stock or prodcution and maybe by the end of the year who knows.
I was looking into curve traer last year too and I spoke with the technician who said the same thing....i.e. by feb, march of last year they would have had one ready.
Now more than a year later, they say end of the year.
I don't think they are going to release anything in my lifetime ahahhahaahah...so I am looking nto another solution.
Is there any suggestion in this regard?

Very frustrating!
I wish they would make a decision one way or the other.

I did look into buying the Elektor kit version but was told by a few people here that it didn't work properly and the last thing I need is test equipment that doesn't work reliably!

I guess we'll just have to keep looking.

If you folks are trying to get a DIY effort going, I'd be interested in helping out with the computer interface/control side. But you really need the basic analog design done first from the DAC out.
