Information

The Oscilloscope SS-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).
