Stop electronic waste, fix it yourself

1.1 Description Kikusui Model COS6IOO Oscilloscope is a universal-type portable Oscilloscope which is capable of 5-channel 12-trace display. It employs a 6-inch rectangular type cathode-ray tube with red internal graticule'. The COS6IOO Oscilloscope is sturdy, easy to operate, and extremely reliable. This scope has many convenient features and special functions which make it an ideal instrument for diversified types of research and development of electronic equipment. It can also be efficiently used in production line maintenance and service applications. 1.2 Features The features of the COS6IOO Oscilloscope can be summarized as ! follows: (1) Ease of use: Light torque lever switches and pushbutton switches are used. These and other controls are laid out in the most convenient locations making the Oscilloscope extremely easy to operate. (2) Clear waveform observation: The cathode-ray tube is a 6-inch large-screen rectangular type CRT with a red internal graticule of 80 mm x 100 mm (3.15 in. * 3.94 in.) The red graticule produces a high resolution background for easy waveform viewing. (3) High acceleration voltage (20 kV): The high acceleration voltage of the CRT ensures a bright trace for observation and photography. (4) High sensitivity and wide frequency bandwidth: The maximum vertical sensitivity is 1 mV/DIV (with x5 MAG) and the frequency response is 100 MHz or greater (-3 dB). (5) High input impedance: The input impedance of CHI, CH2, CH3, CH4 and CH5 (EXT TRIG) is 1 Mfü ±1%, 20 pF ±2 pF, allowing the use of 10x Probes. (6) 5-channel simultaneous display: The C0S6100 employs a new type of vertical mode switching circuit which enables display of any combination of CHI, ADD (CHI ± CH2), CH2, CH3, and TRIG VIEW (CH4 and CH5). Up to five channels can be displayed simultaneously; up to twelve traces can be displayed when in the alternate sweep mode. (7) Trigger level lock: A new trigger level lock circuit eliminates the requirement of triggering adjustments on most signals. (Manual control is still available for triggering on complex waveforms.) When in the alternate triggering mode, stable triggering can be attained even when the signals of CHI, CH2 and CH3 are not time releated. (patent pending) (9) TV sync triggering: The COS6IOO has a sync separator circuit, which allows triggering for TV V signal and TV H signal. It is automatically switched with the TIME/DIV control. (10) B END'S A switch separated from holdoff control knob: The B END’S A switch is installed separately from the holdoff control switch. Holdoff control can be used while in the B END’S A mode. (11) Maximum sweep time 2 nsec/DIV with xlO MAG function: With the xlO MAG function, the highest sweep speed of 20 nsec/DIV can be multiplied by a factor of 10 to attain a maximum sweep speed of 2 nsec/DIV. (12) Alternate sweep: The A sweep and the delayed sweep can be viewed simultaneously in the alternate mode. When in the alternate triggering mode, stable triggering can be attained even when the signals of CHI, CH2 and CH3 are not time releated.
