USB scope

[RS_Jim]

I have an original Parallax usb scope currently connected to my desktop running under winxp. It works great. Now I have a project that I need to run the scope on my laptop which runs on (ugh) vista. First is the software compatible? Second since it has been replaced by the props cope, I haven't been able to find the software. Next I am going to have to measure some pulses that are about 50 volts. Since the scope is rated at 20 volts max I am going to have to use a voltage divider on the scope inputs. Any suggestions for resistance values would be welcome.

Thanks for the help, I need to scope the output of my saltwater pool cl generator as cl levels are excessive. I suspect that the output is always generating a full width pulse rather than narrower pulses when the cl leval is turned down. I need proof of my theory so I can go back on Hayward as the control board is less than a year old and has always generated excessive levals of cl.

The software is availlable here (http://www.parallax.com/StoreSearchResults/tabid/768/txtSearch/Oscilloscope/List/0/SortField/4/ProductID/46/Default.aspx)

Jim,

You will need to use version 5.1.1 for Vista.

Ditto on the HBD!

Thanks for the link Ron. And thanks for bdw from Ron and Jim. at my age it is wonderful to to still be fully functional.
After a little consideration I think I will use 5 meg and 1meg as my input divider which will give me about 5 volts available at the probe input and will not load the circuit.
I will mark this solved. If I can figure out how to mark it!

Just edit the original message (might need to be Advanced mode) and from the dropdown, select "Solved"
