  • Advise on how to measure the SSG with osciloscope

    I finally got inverter and soon i will get the battery with capacity 45 Amp/h to power my oscilloscope.(in my private cellar laboratory all things are independent from the power line grid)
    I want to be sure that i do proper measurement with my scope, so please correct me if i wrong:
    I will connect the oscilloscope probe to transistor emitter and the probe tip to the transistor collector.
    My goal is to see the radiant spikes , because from charge and discharge experiment i am still unsure that my system operates in full capacity.
    As soon as my oscilloscope up i will post youtube video.

    Hi, John K told me:

    "The probe ground should go on the emitter of the transistor and the probe tip should go on the collector of the transistor."

    Seemed to work, but I couldn't see full spike I think because of sample rate of oscilloscope. But I still need to play with it.

      Mike can you post a picture of the radiant spike ?
      I will be able to do the same only in the end of February.
      My oscilloscope is AO 610 Voltcraft and here is tech specs:

        Well this is what I measured with ATTEN ADS 1102CAL--in order to see the spike I figured out that I had to disconnect the charge battery very fast, take a scope shot and reconnect it:

        Versus this I found from PANACEA/BoCaF Bedini pdf from a solid state SSG--I'm not sure of the oscilloscope:



        Sorry, Ukraine, I don't know if those specs would allow you to see it, I'm a beginner with oscilloscope. My scope is 1 Gs/s 100 mhz...

          Yes the first time when i connected my scope i was able to see spike but with disconnected charging battery.
          The attachment which you mentioned, can you repost it, because the link is broken and i canno't access the file.

            Ah, good! Took me awhile to figure it out. Here is another link:

              Today, i will post pictures of my scope, hopefully all work fine.
              Here is pictures:

                In my next charging procedure i will use 1056Ohm resistance.
