The TEKTRONIX 468 Oscilloscope is a portable digital storage oscilloscope with a four-trace, dc-to-100 MHz, vertical deflection system. The 468 combines an easy-to-use storage function with cursor measurement of time and voltage. Measurement values are indicated on a four-digit, seven-segment LED display. NON STORE MODE In the NON STORE mode, the 468 operates as a conventional oscilloscope that can display CH 1, CH 2, ADD, and A TRIG VIEW (external trigger only) simultaneously. The vertical deflection system has calibrated deflection factors ranging from 5 mV to 5 V per division. The horizontal deflection system has calibrated A Sweep rates from 0.5 s to 0.02 µs per division and is capable of operating in the following sweep modes: A,A intensified by B,A alternated with delayed B, and B delayed. The calibrated B Sweep rates are from 50 ms to 0.02 µs per division. The horizontal magnifier circuit feature increases each sweep rate by a factor of 10. This provides a maximum sweep rate of 2 ns per division when the TIME/DIV switch is in the 0.02 μs per division position. STORAGE MODE The 468 digital storage circuitry has a 10 MHz Useful Storage Bandwidth for the acquisition of signals, and will display the acquired waveform with a bright, flicker-free trace. With the digital storage feature, low-frequency signal analysis and waveform measurements-previously difficult or impossible to make-are easily performed. A choice of two standard and one optional signal acquisition modes are available: NORM and ENVELOPE (standard) and AVG (optional). Two storage functions are available to hold a display indefinitely for measurement and comparison: SAVE Storage Mode (stops acquisition) and SAVE REF (holds a reference display and continues acquisition in the selected Storage Mode). Waveform data may be acquired prior to or after the trigger using the PRE TRIG or POST TRIG Storage Window. Time and voltage measurements on the acquired waveform are easily made using the VOLTS and REV DEC 1981 468 Operators 1 TIME Cursor Functions, and the measurement values are indicated on a four-digit, seven-segment light-emitting diode (LED) display.
