    Hi all, I just got a loan of an oscilloscope but have to purchase my own probes. It is a 100MHz scope.

    Do the probes have to match the scope's frequency to work properly or can I use 60MHz probes? I'm thinking 60MHz probes would just limit my range to a maximum of 60MHz, but I'd like to clarify this before unnnecessarily wasting money.

    Thanks,
    Winger

    60MHz probes should be fine for signals under 60MHz. It's not a problem for the probes to be less frequency.

    And they will give you a signal display above 60MHz but there may be some rolloff of the amplitude.

    Ah that's good to know. Though it's unlikely I'll need to go that large in the near future since my college experiments haven't gone above 100kHz so far.

    You may want to check out my video that discusses 1X and 10X probes (as well as some of the other scope "basics" videos on my YouTube channel).
