Re: Oscilloscope bandwidth
I'd be inclined to look for a S/H Tek. 475 - especially one that you can 'test before you buy', since 475s are getting a bit long in the tooth now and many are really starting to show their age. The 475 has a -3dB B/W of approx. 200 MHz.
However, to realise that figure in practice, you do need an expensive Tek. 'scope probe. The effective B/W of any 'scope + probe is determined by the B/W of each: something that is often over-looked.
For myself, my 'scope (a Tek. 2465) is THE most essential item of all my test kit. (Stated B/W 300 MHz; 'flat' to 100 MHz). Now you might not need a high B/W for what you're using a 'scope for today, but in my experience, the day when you will need the 'extra' B/W will almost certainly dawn. Unfortunately, for 'scopes, B/W is expensive.
