The C.R.O.

[N2IXK]

Interesting stuff.

One nitpick, though. That 'scope is a dual TRACE unit, not a dual BEAM.

A dual beam scope actually has 2 separate electron guns in the CRT, with individual intensity and focus controls for each. The primary advantage of a dual beam scope is that it allows the use of different sweep speeds on each channel.

Examples of dual beam scopes would be the Tektronix 555 or 556.
