2247A
The Tektronix 2247A is a 100 MHz four-channel analog oscilloscope, with a built-in 200 MHz counter/timer. (It is unknown if a 2247 non-A model was ever built.)
The 2247A is part of a nearly identical family consisting of the 2245, 2246, 2247A, and 2252.
Channels 1-2 are fully-functioned, and 3-4 are very limited, in both deflection factor and coupling for digital signals.
