Hi all,
I have finally decided to break down and buy a oscilloscope. But I
found I don't know what to get. As this will be by first oscilloscope I
don't need any thing fancy. I don't have a lot of money so a used one
would be fine, if it had a manual or I could get one. I would be
willing to sp...

Hi,
I have the tektronix oscilloscope TD1002, I find the Tektronix current
probe a little bit expensive (A622).
I am setting my eyes on the fluke I310S AC/DC current probe, but I am
not 100% sure it will be compatible with my oscilloscope. Anyone tried
these two combination?
