Analog Oscilloscopes

Alan Wolke W2AEW from Tektronix joins us to talk Oscilloscopes. Alan is a field application engineer for Tektronix, the world's most well-known oscilloscope maker. He also has a YouTube channel that is chock full of great information for those wanting to better understanding oscilloscopes and test equipment in general. Alan joins us for a two part session to deep drive on oscilloscope features and applications. In part one, we introduce the oscilloscope, what it's used for, some introductory concepts, and some comparisons of analog and digital scopes. We also discuss probe quality.

Inexpensive Used Tektronix or HP Scope, Tektronix 465B

Used Tektronix, Hameg, Leader, Kenwood, Hitachi

Don't buy a service grade scope!

Stay away from Vacuum tube models!

Tektronix 465, 475, 485

Tektronix 2215 (2200 series in general) 2225, 2400 series 2445, 2465

Make sure probes are rated for frequency or greater and make sure compensation range contains the input capacitance of the scope
