hi,

im new to the forum. i just started playing with high voltage tubes and im wondering if there are any 100x test probes available anywhere and what considerations are involved since im totaly new to this.

someone said that it is possible to use resistors for attenuation but im not sure how to calculate their value.

thanks

    what kind of HV ? AC DC HF ?


    and what voltages ?

    is this for a Scope or DMM?

    Making an accurate HV probe for ac and dc is difficult. the higher the voltage, the more difficult it gets.
