1. GENERAL
1.1 Description
The 6xxG family oscilloscopes are dual-channel oscilloscopes with maximum sensitivity of 1 mV/DIV, and maximum sweep
time of 10 nSec/DIV. Each of these oscilloscopes employs a 6-inch rectangular type cathode-ray tube with red internal graticule.
623G, 653G and 658G each has a sweep magnification feature with B sweep whereas 626G and 658G provide the read-out function
which enables an easy read out for settings and cursor measured values.
These oscilloscopes are sturdy, easy to operate and exhibit high operational reliability.
1.2 Features
1) High intensity CRT with high acceleration voltage:
The CRT is a high beam transmission, high intensity type with a high acceleration voltage of 2kV for models 622G, 623G,
635G and 626G, and 12kV for models 652G, 653G and 658G. It displays clear readable traces even at high sweep speeds.
2) 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 the temperature change.
3) 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 the troublesome triggering adjustment
not only for displaying signals but also for that of video signals and large duty-cycle signals.
4) TV sync triggering:
The oscilloscopes have a 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.
6) Cursor readout measurement:
The unique easy-to-use cursor and numerical readouts make waveform observations and measurement faster and accurate. The
on- screen cursors provide seven functions, including
∆V, ∆V%, ∆VdB, ∆T, 1/∆T, DUTY and PHASE (for 626G, 658G only).
