Component Tester (V-I Curve Tracer) Using The Oscilloscope XY Mode

[sam.moshiri]

In this video, I've talked about the XY mode/feature of a Siglent SDS1104X-E oscilloscope and used it in a combination with a Siglent SDG1025 waveform generator to show how you can build an interesting component tester (V-I curve tracer) to test silicone diodes, Zener Diodes, Schottky diodes, LEDs, Resistors, transistors, capacitors .. etc. Also, you can use it to learn about the behavior of the components and semiconductors. You only need to follow a very simple circuit (schematic) and hock the probes to the correct circuit points.

In the video, I have tested these components: 330-ohm resistor, 1N4007 diode, 1N4148 diode, 1N5819 Schottky diode, a white LED and a green LED. the memory depth of the oscilloscope was set on 7M.
