Thank you so much for this. I already have a function generator and this makes putting together a curve tracer stupidly easy and accessible. Two components and some connectors.
Ive tried many solutions to build a curve tracer , none of them worked fine , or because the voltage adjust , or because the frequency adjust . Your solution is the best and more flexible (needs a good FG, with "high" voltage, and offset) . Thank you very much to help others .
Thank you so much for the great Video, I just came across your channel I am very new to electronics Can you share the detailed diagrams and schematics of the wiring of the IV tracer box? Thanks again
@@GaryLaRocco Hi Gary, Thank you for your prompt reply. I hoped to get the wiring diagram in your IV curve tracer box. I got the same box with a 10K pot I am unsure about the wiring connections in the box. Thanks
thanks for this video.i have been trying to learn how to do this to test components and learned their properties..like the idea of the pot to adjust resistance. would like to know why is it necessary for two resistors in circuit, since only one channel will show current.I am sure I am missing some basic concept re that.i will try to build on a breadboard.have a cooertrohn 30 mgr function gen.

You can do this with just 10 ohm current sense resistor, which is what w2aew does in his video. I added the 10K pot to allow limiting the current *through* the DUT, which allows you to test with currents down to about 2mA.
I love the neatness of everything you do. I set up the same thing, but I was undecided, so I put several resistors connected with microswitches to set different current steps. The result was not as pretty as yours 😅
I used fixed resistors for the octopus I built. There aren't too many rules for making these - most are made with whatever bits you have on hand, and that works for you. 🙂
I suck at drawing man and I've been doing it for years but I find hobbyist people like myself rarely as neat as a person who plays an engineer in real life haha
Another good video. And thanks for showing us what is in the circuit. I am going to try to build this as well. But I will try it on a breadboard first. I like the idea better of using a signal generator than a transformer from mains power. But another ham like you suggested I could use a 120VAC to 12VAC wall wort to make things less scary to do. Then all would need to be done is bring down 12VAC to the power level needed via a resistor network. Would a zener diode work? Anyways, off-topic for this video. The function generator sounds easier. Thanks for another good video.
You could totally use a 24VAC wall wort to build one. They are readily available and are just a power transformer in a case. A good safe AC source for your bench. For dropping the voltage, I'd just go with a voltage divider. If you have one, a variac paired with an isolation transformer would also work as an adjustable source of low voltage AC.
Hello, I have a 3-in-1 device with Owon HDS2102s model oscilloscope and functional features. Is there any harm in using this project on the same device? I mean, can I send signal through signal generator first and watch the curves on oscilloscope?

amazing. exactly what I was trying to do
Thanks for this!
Thanks for the video. Interesting information. Chewing gum is.a bit distracting I guess.

Hi - full schematic is at 2:55 in the video. Construction is non-critical and can be in any enclosure, or just on a breadboard.

@@avichalid5604 Posted a better schematic in the community section.
Great video. I love old tek gear as well. Im going hunting for a signal tracer on ebay once i sell a piece of gear

if your scope has a built in function generator, you can absolutely use that.

Nice nails hahahahahahaha
