Stop electronic waste - fix it yourself

                                    The SS-5702 is a compact and lightweight oscilloscope which
covers a frequency bandwidth from DC to 20 MHz. The SS-5702
is designed for dual-trace measurement respectively.

The vertical deflection factor is from 5 mV/div to 10 V/div
in a 1-2-5 sequence.

The trigger system provides an internal triggering, external
triggering and TV triggering for TV composite signal.
The horizontal deflection system provides sweep rates from
0.5 ju S/div to 0.2 S/div in a 1-2-5 sequence, 5 times sweep
magnification (maximum sweep rate becomes

0.1 li S/div) and external horizontal/X-Y operation for
Lissajou's pattern.

The cathode-ray tube has a viewing area of 8 divisions
(vertical) I by 10 divisions (horizontal)and high intensity
quantitative measurement is possible by means of the stable
accelerating voltage of 2 kV.

Internal circuit are designed as a full solid-state
structure, and stability and reliability are ensured.
