At work I use a tool called an 'Interceptor' made back in the early nineties, it will do this exercise automatically and cycle through various voltages and frequencies. it has 2 probes and a common ground so you can directly compare a good board with a bad one and overlay the 2 traces and spot a faulty component. The data can be saved to the internal hard drive so you can map a good board and have traces ready to compare should you get a bad board. It is old and looks old too, works with a GUI and maybe a 286 processor in it. Boy is it slow to respond to menu commands. It works though and is useful.

Since your schematic is not complete (where do the ground wired go) at least show the damn thing on the breadboard so I can figure out the circuit.

Thanks for the demo; although aware of its presence, I've never used the X-Y function during tests. I've only ever used it for making patterns on the screen but I like the idea and must try to employ it some time. Kind Regards ... Andy

Great explanation, kind of a octopus circuit with signal gen instead of transformer. Question, do we really need R1? We need resistor just to probe the current, so maybe just r2 with a slight higher value ( to prevent to much current in DUT ) would suffice?

the circruit is incomplete;) ....you need to connect gnd somewhere ! Google "octopus comonent tester" ......you will find many adäqate diagramms . r1 and r2 have to dimensioned so that no Short can accure to the Source (in the o. case a 6....15v transformer) ....its easy ;) .....

Your analogue scope may actually be better for this use. The XY display on many digital scopes can be very poor, sometimes just a series of dots. You don't need a wide bandwidth for this, so an old 5 or 10 MHz analogue CRT 'scope would be fine.

Resurrecting a 6-year-old comment for a fundamental debate, because it's interesting that you point it out. I've got a similar pet peeve with people saying "heighth" (instead of height") when saying length / width / height. Though in this case, it's really hard to tell. For example, I know sometimes I still mouth the "s" or "tz" sound on the end of "megahertz", but just don't always bother enunciating it, since "megahert" is easy to say, but the "s" / "tz" sound at the end of it requires way more precise tongue-and-teeth work to enunciate properly. At your 1st timestamp it seems like it could go either way; I can't tell if he's dropping it, or making the tongue movements and just not enunciating it strongly. Your 2nd timestamp I don't hear any fade-off at the end, so it's hard to tell. This reminds me of George W. Bush and the way he said nuclear ("nuquler"). It's interesting how a lot of words develop differently--depending on your country / state / region--depending on how much effort certain syllables in them take to enunciate. For example, the 2 "megahertz" ones you pointed out, I didn't even notice the first time I watched, since it's so common for people to say syllables like that more quietly than the others.

@TookMe20min2findThis
3 жыл бұрын
He is using an AC signal otherwise all you'd get is a single point on the screen. By using an AC signal of amplitude say +/- 5V, voltage on the X axis can then go from about -5 to 5 volts effectively showing an horizontal line. Assuming the DUT is an open connexion, then no current flows and so that line would lie at 0 volts on the Y axis.. hope that helps.
