Curve tracer information?
« on: November 07, 2024, 12:47:45 pm »
Hi. Hello. I just joined the forum :) Thank you in advance.

What is the difference between the curve tracker in the link and the expensive curve tracker?
Does it work in finding faults in the link?

https://aliexpress.ru/item/1005003504252539.html?sku_id=12000026087459885

Can I find any fault on the laptop motherboard or the PlayStation motherboard with this device?

A proper "curve tracer" has an additional output which can drive the base or gate of a transistor with a current or voltage in multiple steps, so you can capture a full set of characteristic curves of a transistor in one go. The device you linked to does not seem to provide that. It also has limited control over the voltage and current ranges, in a few coarse steps.

But I think you only want to check two-pin components (resistors, capacitors, coils, diodes, or pairs of transistor pins) in-circuit, right? The device should be able to do that. Because you can apparently set different drive voltages, it should be able to test components in low-voltage circuits without causing damage.

I don't know your level of experience. Just to be on the safe side, two more notes -- apologies if this is already clear: You will have to learn how to interpret the resulting I(U) curves, especially in situations where more than one component in the circuit affects the curve in a parallel or series configuration. And you will need to connect an oscilloscope to the device to see the results!

No.

"Can I find each and every fault?" No.
"Are there any faults I can find with this?" Yes.

The apparatus in the link you provided can compare two components.
If you have a healthy PCB and a non working PCB you can try to discover where the difference is.

I wouldn't call this a curvetracer, but a component tester. (At least Hameg calls it that way).
