-The Tektronix 2246 is a 100MHz four channel* analog oscilloscope, with limited automatic measurement capability. It's part of a nearly identical family consisting of the [[2245]], 2246, [[2247]], and [[2252]].

+The '''Tektronix 2246''' is a 100 MHz four-channel analog oscilloscope [[introduced in 1987]]. It was updated to the [[2246A]] in 1988.
-Two channels are fully-functioned, and two are very limited, in both deflection factor and coupling.
+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 measurement, 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.

+The input buffer amplifier in the 2246A is the [[165-2232-00]].
