Need help with some measurements.

jw0752

I need some help collecting data about Oscilloscope Probes. I am thinking of making some low frequency Non-Slip probe tip adapters for Oscilloscope probes. With the limited number of Oscilloscope probes with in my reach it does not look like there is any standardization.

As you can see the two probes that I own each have different diameter probe tips. It would help me plan my project if I could find out what the diameter and length of oscilloscope probes from as many of you as possible. Please measure length of the consistent diameter of the tip and also the diameter itself. I can accept measurement in inches or millimeters. Here is what I hope to be able to build without having to custom make each one.

Your help would be appreciated.

    I was thinking maybe foil + puncturing holes and then scanning it using my high-resolution scanner might actually not be a bad way to do it given the tools I have. Or maybe removing the probe tip for those that are removable and scanning that directly.

     

    I'll let you know if I turn up any results - got some Picoscope, Rigol, R&S, Vellemann and ''generic" probes here which I regularly use. Have some Keysight at the uni lab.

    - I decided to give my improvised method a go - I grabbed a piece of foil and corrugated cardboard, punched the probe tip through the foil into the cardboard and scanned the foil at 4800dpi to judge the size of the depression as a way to measure the probe tip diameter.

    My pin diameters measured out to be (using Photoshop to the nearest 0.1mm):

    R&S - 0.5mm

    Rigol - 0.7mm

    Generic #2 - 0.7mm

    Generic #1 - 0.8mm

    Pico - 0.9mm

    Velleman - 1mm

     

    Of course, I'm not sure how accurate it is, but judging from the R&S RT-ZP10 specs which shows the gold plated spring tip (that I'm using) is 0.5mm, I'd have to say that my measurement mode is likely to be accurate "enough". Sorry, no information on pin length as yet image.

    You have awesome ingenuity. Thanks for the effort above and beyond the call of duty.
