The D67 is a 25 MHz, all solid state dual-trace oscilloscope. An 8 x 10 cm mesh CRT provides a bright and clear display.

The dual-trace vertical system displays either channel separately, adds channels algebraically, alternates between channels or chops between channels at 80 kHz rate.

The delayed sweep feature permits close examination of any part of a complex waveform and allows for an accurate time measurement of the input waveform.

The solid state design, using FET input circuitry, provides minimum drift and fast stabilization time.
