The '''Tektronix 2246''' is a 100 MHz four-channel analog oscilloscope [[introduced in 1987]]. It was updated to the [[2246A]] in 1988. | |||
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 | 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]]. | |||
