2247A

Manuals – Specifications – Links – Pictures

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.

Smart Scopes like the 2247A has four channels, and advanced features like Auto Setup, Tracking Cursors, Voltmeter, Integrated Counter/Timer, and Store/Recall of 20 front panels setups.
