* Vertical axis of low input capacitance (22 ±3pF) for 2 -
channel operation provides high sensitivity and wide
band-width (10mV/div, 15MHz).
* High sensitivity CRT with excellent beam permeability
has sufficient brightness for measurements of fast speed
pulses of high frequencies.
* 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.
* 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.
* CH1 and CH2 can be individually synchronized (internal
syncronization).
* 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.
* Mode selector switch is provided for measurements of
sum and difference between 2 channels.
* Low power consumption (23W) for cool operation.
* All component parts are cleverly mounted on circuit
boards for improved reliability.
* Trace rotation system for easy adjustment of horisontal
trace.
* The adoption of IC's throughout circuitry assures high
performance and improved reliability.
