High voltage oscilloscope probe
<< < (5/5)
alm:
Interesting app note, though from a (for me) unknown source. Clearly the parasitic capacitance is increased when filled with silicone oil since they have to more than double the maximum value of those trimmer caps. I wonder how much this will affect the input impedance, transient response / bandwidth and voltage derating.

This thread discusses replacements, and there is some discussion at the end about filling the probe with silicone oil and its effect on compensation and bandwidth, although nothing definitive. Pay extra attention to posts by user ditter2, who was the engineering manager for the redesign project (P6015A).

My homemade probe

HighVoltage:
For up to 40 kV I also use the Tektronix P6015A
Anything higher, I use self build voltage dividers for up to 100 kV

What accuracy do you need in the probe?
