1.1 Descriptionff  The GOS-6xx Family oscilloscopes are dual-channel oscilloscopes with maximum sensitivity of lmV/DIV. and maximum sweep time of 20 nSec/DIV. Each of these oscilloscopes employs a 6-inch rectangular type cathode-ray tube with red internal graticule. GOS-623B and GOS-653 eachhas a sweep magnification feature with B sweep whereas GOS-625 and GOS-645 provide the read-out function which enable an easy read out for settings and cursor measured values. 
  These oscilloscopes are sturdy. easy to operate and exhibits high operational reliability.

1.2 Features
1). High intensity CRT with high acecleration voltage The CRT is a high beam transmission, high intensity type with a high acceleration voltage of 2.2KV for models GOS-622B. GOS-623B andGOS-625 (and 12 KV for models GOS-652, GOS-653 and GOS-645). It displays clear readable traces even at high sweep speeds. 
2). High stability with less driftThe oscilloscope employs a temperature compensation circuit which is newly developed to reduce the drift of base lines and DC balancedisturbance caused by temperature change.
3). A trigger level lock function which makes the triggering adjustment unnecessaryA new trigger level lock circuit is incorporated. This circuit eliminates the procedures of the troublesome triggering adjustment not only fordisplaying signals hut also for that of video signals and large duty-cycle signals.
4). TV sync triggering The oscilloscope has i sync separator circuit incorporated within the TIME/DIV switch for automatic triggering of TV-V and TV-H signals. 
5). Linear focus Once the beam focus is adjusted to the optimum position. it is automatically maintained regardless to the intensity change.
