Charles Hansen's Semiconductor Tester

[spzzzzkt]

Hi,

I finally tracked down a copy of Charles Hansen's "Semiconductor Tester" article from Popular Electronics May 1999. The device is a curve tracer which hooks up to a 'scope and looks an easy build given all the parts are still available.

I was curious if anyone had built this and could offer an opinion? Were there any suggested updates or errata for the design?

cheers

Hello,
I found two kind of curve tracer in the market one with own display and other use osciloscope as display. the problem are they are expensive to my wallet I dreaming one day some one can take care to write a program to made a pc control with cheap budget curve tracer

Don't know if you've seen this device:

software is pretty basic but a free download.

If Charlie has no objection's i'll post the schematic and part list for his curve tracer.

hello,
already tried it honestly its just a basic unit not enough voltage and facility ?
I think I ask so much for something free

I looked to find the original publication of Hansen's Semiconductor curve tracer, but could'n find it anywhere.

I am currently involved in collecting informations to built a curve tracer adaptor for X-Y Oscilloscope.

Please, can someone direct me to Hansen's construction project?

Thanks!

hello.
if i remember correctly elektor had a transistor curve tracer for oscopes in the nineties..............

Erno Borbely published a sophisticated design, iirc.

Fwiw.

Also you can look up the schematic for a B&K (the test equipment company, not the mic) transistor curve tracer that used an external scope. It was useful and fairly simple.

thanks, that was a good suggestion!


i'll save some of you some work.
one link is here

bear,

I imagine you are referring to the B&K Precision 501A model. I had the informations about this one.

mlloyd1,

When I click to your link, I am redirected to this thread. I don't know if the link is bad, or if I am not yet out of the "initiation purgatory" period... There is things, like sending PM, that I am not allowed to do at this moment.

Thanks for your inputs, I really appreciate it.

Very usefull info.

mmloyd 1,

Link indeed refers to this thread
Can you check again and repost?

Thanks so far.
