2246

Manuals – Specifications – Links – Pictures

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 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.
