I recently bought this little gem. I will be doing a full review on it because I am excited about the possibilities of this compact analyzer. It's a company in the UK call Peak Electronics, and so far this device is impressing me. However, I have only tested it for a day or two now and want to put it through some more advanced testing. The volume of devices it can detect accurately and reliably is also impressive. As a standalone unit, it is very handy but adding the USB capabilities and the software which is a free download or comes with the unit on a free 512MB USB stick, gives this unit the ability to graph performance curves of semiconductors with a fair degree of configurable parameters. It's about 175.00 US Dollars.
Here is the official video for the Atlas DCA Pro.

More to come.

I also like it very much, it is a really nice and usefull tool

Thanks for the link. I feel it's almost a must for the lab. It sure makes my life a lot easier.

Do you guys know if this version supports Idss and curve tracing for jfets?
The previous one had serious restrictions due to its battery supply

I'll have to dig up a jfet to test, but the software shows a couple graphs available for jfet curve tracing. They are id/Vds and id/Vgs. Looks like id/Vds is Vdd from 0V to12V and Vgs from -10V to 10V. Likewise, id/Vgs is Vgs from -10V to 10V and Vds from 0V to 12V. Hope this helps!

Thanks a lot
does it refer to any current limits?

I don't think it will detect max current limits on fets because many have fairly high current ratings and the DCA75 Pro is a small unit and not capable of large current testing. I believe that's what you were talking about, please correct me if I'm wrong.
I attached some screenshots from an old jfet I dug up so you can get an idea of the curve tracing. I think the DCA75 Pro is a very useful tool unless you have the money for an Agilent SMU, then this works a treat!

I just got my unit and have played a little with ID'ing parts. I don't have any failed parts to check but will this unit ID a failed part and indicate that it is indeed failed?
-
I just got one 2 weeks ago. Quite a cheap, fast and functional little device. Worked like a charm for all components I tested. Last used it for sorting out bad output transistors for amplifiers. Also comes in handy for selecting matched output transistors.
-
What did it display for the bad transistor?
-
If I remember correctly something like "Bad component detected or test leads shorted". They all had a short circuit. So I don't think there was any way to detect they where working transistors before they blew up ;)
All (HV)diodes, zeners, normal power and dual color leds, voltage regulators, transistors and fets where correctly identified. The software works like a charm too. Its simple fast and intuitive.

Love mine. Does anyone know if there is an API to allow me to use it for bulk testing?
