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 ...

High voltage ripple measurement using a 1000:1 probe
I am measuring the DC voltage ripple at 400V provided from CAEN DT5534EM by connecting the output to the oscilloscope (AC coupling) through a 1000:1 probe. From the picture below, the ripple is around ...

Differential measurements with high voltage oscilloscope probes
This interesting post about differential measurements with a scope has raised a few questions in my mind.
I have read about true differential scope probes and they seem to be very expensive. Would ...
