The Tektronix Type 3T4 is a sampling sweep plug-in for 560-series scopes that is remotely programmable, allowing computer-controlled measurements of high-speed repetitive waveforms. It interfaces with a 6R1A plug-in in a Type 567 scope. It was introduced in 1965.

Specifications

The equivalent-time sweep rate ranges from 1 ns/div to 200 μs/div. There is a 10x calibrated horizontal magnification mode that can be selected, providing 100 ps/div horizontal scale. The maximum trigger frequency is 1 GHz.

The sweep can be controlled by the staircase ramp generator in the 3T4, manually by a front-panel knob, or remotely by a control voltage sent to the 3T4.

The remotely programmable functions are

  • Equivalent-time sweep rate
  • Delay time
  • Samples per sweep
  • Normal or single-display mode
  • Single-display start
