The '''Tektronix 2246''' is a 100 MHz four-channel analog oscilloscope.  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 2246 includes many of the same features of the 2245A and adds auto tracking SmartCursors which track the selected measurment, trigger level, or ground. There are Labeled Volts Cursors with Ground-Referenced Readings and On-Screen Readouts; Hands-Off Voltmeter Measurements of DC Volts, +Peak and -Peak Volts, and P-P Volts; SmartCursors Integrate Voltage, Time, Frequency, and Phase Measurements, and are available in ALT and B Horizontal Modes.

{{Spec | Deflection| CH 1, CH 2: 2 mV/div to 5 V/div in 1-2-5 seq; CH 3, CH 4: 0.1 V/div and 0.5 V/div, all ±2%; BW Limit: 20 MHz ±15%  }}

{{Spec | Maximum Input Voltage| 400 V (DC + peak AC) or 800 V (p-p ac at ≤ 10 kHz) }}

{{Spec | Sweep Speeds| A Time Base: 0.5 s/div to 20 ns/div in 1-2-5 seq; B Time Base: 5 ms/div to 20 ns/div in 1-2-5 seq (×10 magnifier to 2 ns/div) }}

{{Spec | Trigger| DC, Noise Reject, HF Reject, LF Reject, AC, TV Line, TV Field }}
