3/18/01 - Just got a Fluke 105B ScopeMeter from E-Bay. This is a portable, two channel, 100 MHz, digital storage oscilloscope and multimeter. It came with an optically isolated, RS-232 adapter and Windows 95 software . I spent the weekend learning how to use it. The following screen shots show my results so far.
Next, I need to get some 50 W shielded cable so I can hook up my 500KV probe, and some wire mesh to build a Faraday cage for the 'scope.
10/20/01: I've modified my 500KV probe with
a BNC bulkhead jack so that it can accept 50 W
shielded cable. I bought two 10' and one 1' BNC terminated cables
and two jack to jack connectors so that I can connect them all together.
I also made two heavy ground cables from 6 AWG welding cable and large
copper battery clips. In use, the 1' long cable is connected to the
oscilloscope and the ground clips are conncted to the jack to jack BNC
connector that connects the 1' cable the long cable or cables. I
also bought a BNC to banana jack adapter, so that I can still use the modified
probe with a digital multimeter.
In order to keep page sizes reasonable, I will start new pages for additional measurements.
