Computer controlled curve tracer

Apr 02, 2006 3 Replies

Please forgive me if this is not the right group and if it isn't could someone point me in the right direction. I would like to build and program a curve tracer that interfaces with my computer. Something like a Huntron. The basic circuit for a basic curve tracer isn't that hard to build. I built a simple one for my scope and it worked pretty good. I would like to be able to have up to


100 channels to input and display and compare signatures against other known working boards or chips. What I need to know is what type of hardware and software package should I start working with? Is there a PIC chip that can do this and if so what one would it be. Or is there some other type of hardware/software like LabView that I should use. I

am on a budget but I do want flexability in case in the future I want to add featues. There are so many things to choose from I don't know where to start. I really do appreciate any experienced help with this.



I wanted to buy a package already built like the ABIElectronics.co.uk system but the price is just to high. Could someone point me in the right direction.



Thanks Uriah



Nifty idea, I may make myself one, thusly...

Program a PIC with serial communication with a PC COM port. Have the PIC take basic commands from the PC as far as setting up the drive voltages and currents and such. Then have the PIC take the measurements and send them back to the PC.

The PC program can then be as elaborate as necessary. It simply calls out any number of tests point by point.
