11:25 Diode across the LED should be the other way round, in reverse parallel.
A U.S.Navy technician in the late 1960's was given the credit for developing this handy device and it was called an octopus because of all the wires hanging off it. Now that I am retired maybe I'll finally build one to play with ?
Gracias amigo
De nada!
I need one of these haha 😄 I should build one in the next month or so would be handy with my recording equipment repairs
These are perhaps the best diagnostic tools to see the behavior of the component
Thanks. I've seen people use curve tracers before but didn't realise how they worked. Quite simple but cunning.
Years ago I built a curve tracer out of Popular Electronics Magazine. My brother broke into my storage and sold off all of my Lab equipment years ago. I'm just starting to build up my Electronics Laboratory Bench All over again. Replacing everything makes me less angry. I will make another curve tracer. Everythings replaceable.
If I were in your situation this would have been a remake of the Kain and Abel story.😁
Unless I have completely misunderstood (which is quite possible), in the circuit diagram of the component tester at 10:15 the scope connections X and Y are reversed.
Really useful.....many thanks, Bill.
In my opinion one of the most useful gadgets. I'm using a Hameg component tester for nearly 25 years to check IGBT's and other power components. It never failed.😁
TY
Nice donation!
Hello dear colleague. I am Mauro, a technician and curator at the Electronics Museum. Greetings from Brazil for the excellent video and thanks for sharing!
Mario where is the electronics museum?do they have a website? thanks

I made one of these back in 1985 with a 12.6 v ac Transformer. You can also change your H and V controls on your scope as well to view the complete waveform if it falls outside the screen. I would be curious of the 3 ac output voltages from the kit.

Excellent video.
I face problem when using Tunnel Diode.
Can you please suggest how to deal with Tunnel diode?
Не хватает характеристик катушки индуктивности и куда массу цеплять у щупа. Почему не указали ?
Hii
This tester is very simple. You just need to make two-lead sine wave generators. x.y -0-180 degree phase angle inverse sine. Drive with popular ic8038 and even better ad9833 generator .or simple oscillator .transformer or transformerless .opamp. voltage is adjustable from 5v ac to 24v and frequency from 50hz to 1000hz. current should not exceed 1ma to 5mA. it is enough to know the logic of a resistor and a coil.
Thanks, Bill. Excellent as always. Could you build one of these using a signal generator?
Indeed you can...
@@LockdownElectronics please I would love to see this in a future video!
There is a commercial version called a Huntron tracker. I believe it uses 400Hz. It also has a relay and two "hot" leads. You would hook one lead to the chassis ground and it would switch back and forth between the other two leads for the DUT. If you had a stereo amp with one blown channel you could put a lead on each channel in the same component and see if the V/A signature is the same. As you worked your way through the board, when the signal would change from L-R you knew where the problem was.
@@alanduncan3710 Great idea with stereo amps to track measurements across channels. Why didn't I think of that. Build 2 and then you can check them. Thank you.
thanks for this educational video.
I am trying to follow on my breadboard.
seems like every I-V tester I have seen uses different voltages, resistors,so get different curves on screen.
is there a pattern or formula to decide how much AC voltage, resistors number and sizes to use as voltage dividers In making one on breadboard.capacitors seem to show up as some sort of circle, but diodes have great variety of shapes.
John
What happened to the promised screen shot of a Digital scope being used in this way?
I have never understood the point of a two wire curve tracer?
You need THREE terminals, because the base/gate also need to be current/voltage controlled (stepped actually).
Wonder if it works different with a digital scope?
About the same, depends on how fast your screen refreshes. Looks prettier on an analog scope though.
Wath are the BOX labled DUT in the two curve tracer schematics ?
DUT = Device Under Test
@@LockdownElectronics If I understood correctly this means it will work on single channel digital oscilloscopes as well.
👑👍🏻💯👍🏻👍🏻👍🏻👍🏻
This schematic is based on old schematic, what military used back in days for quick component diagnosis.. 😉 I have this schematic in old magazine. When limiting supply voltage, this tracer can help diagnose problems with digital circuits and even showing dead ICs.. But, that part now is obsolete with modern stuff, because everything is more complex and lots of stuff is done in firmware using few chips and not in jellybean hardware with easy replacement..
Great video anyway! 👍
Коллега,благодарю за информативное видео.Вопрос-собирал подобную схему,не могу избавиться от зеркального отображения по оси "Y".Как Вы решили эту поблему?
