* The adoption of ICs throughout assures high performance and improved reliability. * Vertical axis of low input capacitance (22 ±3pF) for 2-channel operation provides high sensitivity and wide band-width (10mV/div, 10 MHz). * The high voltage power for CRT as well as the power for other circuits is fully stabilized because of the use of DC-DC converter, thus the sensitivity and brightness are completely free from effects of voltage variations. * Low power consumption (20W) for cool operation. * X-Y operation is possible with CH2 amplifier used as X axis. The horizontal axis sensitivity is as high as 10mV/div, permitting accurate calibrations. * Time base switch allows changeover between CHOP and ALT and between V (vertical) and H (horizontal) of TV sync separator circuit, automatically and electronically. * At AUTO position of TRIG LEVEL, it is possible to check the brightness at no-signal time and to adjust triggering level of input waveforms. * All component parts are cleverly mounted on circuit boards for improved reliability. * Easy correction of horizontal trace angle with unique trace rotation system.
