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.

Sample rate 16 MS/s
Memory 16 kSamples
Deflection 5 mV/Div – 5 V/Div in 1–2–5 sequence, 0.5 mV/Div bandwidth limited to 1 MHz
Input impedance 1 MΩ // 25 pF
Sweep (non store mode) 0.1 μs/Div – 0.5 s/Div
Sweep (store mode) 2 μs/Div – 50 s/Div
Interfaces RS232C (printer/plotter/PC)
Power 85 W max.
Weight 7.9 kg (14.7 lbs)
