6 FAQs about [How to add filter capacitor to oscilloscope]

How to test a capacitor using an oscilloscope?

Using an oscilloscope, we can measure how long it takes to charge the capacitor to 63.2% of the initial voltage. We can rearrange the previous formula to calculate the value of the unknown capacitor. For this test, I am using a (4.7kΩ) resistor in series with the capacitor. The signal generator acts as a power source and sends the square wave.

How do you charge a capacitor using an oscilloscope?

The oscilloscope on the right will measure the time it takes to charge the capacitor. One of the PWM 2 pins of a Raspberry-Pi Pico will generate the square wave signal to charge and discharge the capacitor. I could have used any microcontroller such as an Ardiuno, ESP8266, or ESP32. I will use the PWM pin 16 from the RPi Pico for this experiment.

How do I set up an oscilloscope?

Plug your coaxial cable into the oscilloscope. Connect the center (axial) portion of the cable to the signal, and the side (usually an alligator clip) to ground. Set the oscilloscope to AC coupling for now (I'll explain a little bit more about this at the end of the tutorial) * This program is free software; you can redistribute it and/or modify

How to use a capacitive divider in an oscilloscope probe?

From Introduction to oscilloscope probes. The trick is to use two potential dividers; one resistive and one capacitive. Since we've got a ratio of 9:1 with the resistive divider we need to do the same with the capacitive divider. Remember that the capacitors impedance is given by ZC = 1 2πfC Z C = 1 2 π f C so

How do you compensate an oscilloscope?

Most oscilloscopes have a square wave reference signal available at a terminal on the front panel used to compensate the probe. General instructions to compensate the probe are as follows: Attach the probe to a vertical channel. Connect the probe tip to the probe compensation, i.e. square wave reference signal.

How to measure resonance frequency with oscilloscope?

For some people the curve will appear as such, for other you might have to tweak around a bit. Make sure scope probe is set to 10x since we need the decoupling capacitor. Also set time division at 20us or less and then decrease the magnitude to less than 1V.
