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.)

Channels 1-2 are fully-functional, whereas 3-4 are limited in both deflection factor and coupling, as they are intended mainly for digital and trigger signals.

The 2247A includes the same features of the 2246 plus a Counter/Timer (C/T) integrated into the trigger system to provide many automated counting and timing measurements of frequency, period, width, totalize, frequency ratio, gated frequency, gated period, gated width, gated events, delta time, one-over-delta time, phase, rise/fall time, and propagation delay, using an internal or external frequency standard.
