The '''Tektronix 2246''' is a 100 MHz four channel analog oscilloscope, with limited automatic measurement capability.


It is 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.  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.


Two channels are fully-functioned, and two are very limited, in both deflection factor and coupling.  
The 2246 includes the same features of the 2245 plus STORE/RECALL SETUP up to different 20 front panel setups and can be arranged in sequence as required for specific applications.  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 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 the same features of the 2245 plus STORE/RECALL SETUP up to different 20 front panel setups and can be arranged in sequence as required for specific applications. 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.
