Information
The Oscilloscope 5702A/03A/05A/06A is an indispensable
instrument for the production lines a and
maintenance/servicing as well as research and development of
electronic devices and equipment.
This is a measuring instrument which has pursued not only
functionality, but also operability, high accuracy and
stability.
The major features of this instrument are as follows.
• The vertical deflection system, with the frequency band
widths of DC to 20 MHz SS-5702A 03A), DC to 30 MHz SS-5706A DC to 40 MHz SS-5705A has the DUAL function SS-5702A 03A) which allows 2-phenomenon (in the CHOP or
ALTERNATE mode) observation, and can provide the
2-phenomenon (in the CHOP or ALTERNATE mode) and
3-phenomenon (in the CHOP or ALTERNATE mode) 6-trace display.
It can also measure the sum and difference of two signals
(by ADD). Since the maximum input sensitivity is 1 mV/div.
for both CH1 and CH2 due to the PULL x 5 MAG function,
microvoltage can be also measured accurately.
The horizontal deflection system has a maximum sweep rate of
50ns/div. by the PULL x 10 MAG SS-5702A 03A), of 20
ns/div. by the PULL x 5 MAG SS-5706A function, or of 10
ns/div. by the PULL x 10 MAG SS-5705A and can measure up
to high-speed phenomena accurately.
It is possible to have the delay sweep function (SS
-5705A/06A only) and observe TV signal waveforms due to X-Y
operation and TV-V, TV-H (TV-V only for SS-5702A triggering.
The CRT is 6-inch (150 mm) rectangular with nonparallax
internal graticule. It has a display area of 8 div. (length)
x10 div. (width) (1 div. = 10 mm) and allows high-luminance
waveform observatiion due to the stabilized acceleration
voltage of about 2 kV SS-5702A 03A) and 12 kV SS-5705A 06A).
