Versatile Triangular Sweep Generator

Abstract

A versatile, all‐electronic cyclic linear‐sweep generator is described. This device produces a symmetric or asymmetric triangular waveform of high quality with sweep rates continuously variable from 5 mV/sec to 2000 V/sec, independent of amplitude; positive and negative sweep limits are independently variable from 0–3 V relative to a reference level which is itself variable with respect to signal ground. Provision is made for controlling the output voltage at a preset level prior to initiation of the sweep, and the sense of the initial sweep may be selected. The cyclic sweep may be halted at either limit, either mechanically or electronically. An auxiliary output provides a square wave with peak‐to‐peak amplitude equal to the peak‐to‐peak amplitude of the triangular waveform, based at signal ground, and with period regulated by the sweep rate controls.
