Homemade high-voltage probe not dividing the voltage by proper amount

I have tried to build a homemade high-voltage probe, as commercial ones are too expensive. Firstly, I connected a 1 MΩ resistor to a ~1.4 V battery which gave an output voltage of ~0.2 V. By using ...

High-voltage oscilloscope probe

I need to measure a high-voltage signal (1kV) with an oscilloscope without a commercial high voltage probe. So I have to design my own 100:1 probe. The oscilloscope has an input impedance of 1MOhm and ...

How does capacitive coupling work for measurements

The context is the measurement of engine speed on a vintage car that uses a classic Kettering ignition system. Essentially, a voltage pulse of tenths of kV is generated on a high tension (HT) lead. ...
