Hi All,
Here's a question that's been knocking around in my head for a while.
I recently bought a Hitachi V1050 'scope - it's a great instrument but, in common with other 'scopes of the same make that I've used, very sensitive to external magnetic fields.
My preveous instrument (an Iwatsu) used to live with my function generator balanced on top of it - if I try the same trick with the Hitach the trace is unusably wobbly.
Now, I'd like to be able to stack equipment in close proximity as I'm quite tight for space, but I'd also like to have confidence that my trace is as flat as possible when grounded. So...
Would it be possible to add any screening/shielding? Of course, mu-metal springs to mind, but I know very little about it besides the name. Is it available to the hobbyist (in the UK), it is affordable, what forms are available, and how it it best worked? Or am I barking up the wrong tree?
This is a [one of many] rainy-day project, but any opinions would be very welcome.
