Oscilloscope hooked to SSG ?

[TinselKoala]

That's actually a pretty nice little scope for "amateur" use!
It's a dual-channel DSO, so you can hook up one channel to your input and the other to your output at the same time. It has 1 megohm input impedance so your (low freq) circuit won't notice it's there. And it has "single-shot" capability, which is extremely useful when examining, well, single shots. Like single cap discharges into a coil, for example.
The 25 MHz bandwidth won't be much of an impediment for the Bedini work, although it is nice to have a fast rise-time for this kind of "pulsy" work.

I looked at the manual, and the math functions are kind of limited. It will only do addition and subtraction between traces, not multiplication or integration over time. However, the "measure" function will give "rms" voltages, but I couldn't find out whether that is accurate for all waveforms or only sinusoids. Still, it will be useful for your power measurements.

In any case, you should have a lot of fun with this simple scope, and it should prevent you from making some fundamental errors that folks without scopes often make.

Nice little scope


Your inputs are rated 300V max, be real careful you don´t zap it. Only takes one careless touch and your input stages get fried or even worse at higher Vs.

Whenever I work with coils I hang my regular probes up and just do everything with 100x probes. You can get fairly good value 100x probes on ebay:

If you make your own attenuator then you could make one using a small metal box with a BNC socket on one side and a BNC plug on the other and then put your divider resistors in the box. That way you can just use your probe without having to worry about touching high V.

   Then you could do like me, I bought an old "tube" type scope and use it first to see what the voltage might be. I have used it on 1000v
readings and have to guess as to its exact but sure cant kill it. Then I go to my Tek 250mhz to see things right. After frying my 60mhz
scope, I am real careful.

   Could I inquire as to where you came by it? I have been looking for one so as to have a totally isolated unit. The 60mhz one I looked at
would run on batteries as well. Thanks

Hi, I've bought mine from Saelig http://www.saelig.com/miva/merchant.mvc?Screen=PROD&Product_Code=PSSA002&Category_Code= they also sell one with a battery

I just picked up one of these, the price was good for a 60Mhz.
