2247A

The Tektronix 2247A is a 100MHz four channel* analog oscilloscope, with a built-in 200MHz counter/timer. It is unknown if a 2247 (no A) was ever built. It's part of a nearly identical family consisting of the 2245, 2246, 2247, and 2252.

Two channels are fully-functioned, and two are very limited, in both deflection factor and coupling.
