• Notes
• The Tektronix Type 535A is a DC-to-15 MC Oscilloscope with a wide range of sweep delay. It is easier to operate and offers higher performance than its predecessor, the Type 535.
  Color-correlated controls contribute greatly to ease of operation. Other contributing factors to easy operation of the Type 535A are simplified panel layout and horizontal display control, single-knob sweep and calibrator controls, and internal triggering for sweep delay.
  Greater reliability has been achieved through use of the new frame-grid twin triodes, and a change to silicon diodes in the power supplies. Performance improvement includes an extra 5 mc in vertical response and wider range of sweep delay.
  
  Simplified panel layout. Color-correlated controls.
  Two Kinds of Sweep Delay
  Triggered (jitter free—delayed sweep is started by signal under observation. Conventional—delayed sweep is started by delayed trigger.
  Greater Calibrated Delay Range
  1 usec to 10 sec, continuously adjustable (2 usec/cm to 1 sec/cm).
  DC-to-15 MC Vertical Amplifier
  All Tektronix Type A to Z Plug-In Preamplifiers can be used for signal-handling versatility.
  Two Time-Base Generators
  TIME BASE A - 0.1 usec/cm to 5 sec/cm in 24 calibrated steps, continuously variable from 0.1 usec/ cm to 12 sec/cm. 5-x magnifier increases calibrated range to 0.02 usec/cm. Single-sweep provision for one-shot applications.
  TIME BASE B—Also functions as delay generator.
  18 calibrated steps from 2 usec/cm to 1 sec/cm.
