Features
High intensity CRT with high acceleration voltage. The CRT is a high beam transmission, high intensity type with a high acceleration voltage of 2.2 KV. IT displays clear readable traces even at high sweep speeds.
High stability with less drift. The oscilloscope employs a temperature compensation circuit which is newly developed to reduce the drift of base lines and DC balance disturbance caused by temperature change.
A trigger level lock function which makes the triggering adjustment unnecessary. A new trigger level lock circuit is incorporated. This circuit eliminates the procedures of teh troublesome triggering adjustment not only for displaying signals but also for that of video signals and large duty-cycle signals.
TV sync separator circuit incorporated within the TIME/DIV switch for automatic triggering of TV-V and TV-H signals.
Linear Focus. Once the beam focus is adjusted to the optimum position, it is automatically maintained regardless to the intensity change.
