Information

General Information The Tektronix Type 535A Oscilloscope is a wide-range general-purpose laboratory instrument providing accurate measurements in the dc to 15 me range. The Type 535A can be operated with any Tektronix letter-series Plug-In to satisfy the requirements for virtually any application. Special circuits incorporated in the Type 535A Oscilloscope permit an accurate, continuously variable delay in the presentation of the sweep from 1 microsecond to 10 seconds after receipt of a triggering impulse. This feature permits observation of a small portion of the normal sweep, accurate measurement of waveform jitter, precise time measurements, as well as many other uses. Vertical-Deflection System All specifications for the Vertical-Deflection System of the Type 535A depend upon the Plug-In unit used with the instrument. The following specifications are given assuming that a Type K Plug-In Unit is used. Sweep Rates Time Base A-0.1 microsec, Js to 5 seconds per centimeter in 24 accurately calibrated steps. An uncalibrated control permits sweep rates to be varied continuously between 0.1 microseconds and approximately 12 seconds per centimeter. Calibrated sweep rates are typically within 1 %, and in all cases within 3%, of the indicated sweep rate. Time Base B—2 microseconds to 1 second per centimeter in 18 accurately calibrated steps. Sweep rates are typically within 1%, and in all cases within 3%, of the indicated sweep rate. Magnifier Provides a 5-times magnification of the center 2-centimeter portion of the Oscilloscope display. Extends the fastest Time Base A sweep rate to 0.02 microseconds per centimeter and the fastest Time Base B sweep rate to 0.4 microseconds per centimeter. Bandpass Risetime Triggering Modes DC to 15 me (=3-db down at 15 me) <0.024 microseconds External Horizontal Input Deflection factor—approximately 0.2 to 20 volts per centimeter, continuously variable. Frequency response—from dc to 350 kHz. Response down 3 db at 350 kHz. Time Base A—Automatic, AC, DC, AC Low Frequency Reject, and High Frequency Sync. Time Base B—Automatic, AC, and DC. Triggering Signal Requirements Internal triggering—a signal producing 2 millimeters of vertical deflection except 4 millimeters is required in the DC and Automatic modes. External triggering—a signal of 0.2 volts to 10 volts. Sweep will trigger on larger signals, but TRIGGERING LEVEL control operates over a ±10 volt range. Automatic mode requires 0.4 v. High Frequency Sync.—Assures a stable display of sine wave signals to approximately 30 me. Requires a signal producing 2 centimeters of vertical deflection or an external signal of more than 2 volts. Delayed Sweep Sweep delay continuously variable from 1 microsecond to 10 seconds. Actual delay steps (between 1.00 and 10.00) are within 1 % of the indicated delay from 2 /nsec/cm to 0.1 sec/ cm; within 3% from 0.2 sec/cm to 1 sec/cm. Incremental delay accuracy is within 1% ±4 minor divisions. Time jitter—1 part in 20,000.
