Contents
What do we need ?
- Cheap scopes for casual use. 10 to 20 scopes ?
- About 100MHz BW
- 4Ch
- Middle range scopes. 4 scopes ?
- 200 to 500MHz BW
- High performance scopes. 2 ?
- GHz class
- Logic analyzer option (Mixed Signal Oscilloscope)
- Isolated input scopes. x2
- Active high impedance probes (FET) x 4 ?
Probably it is a good idea to buy all scopes from one company.
