Information

1.1 Equipment Description The C0S6100M is a solid state, five channel, twelve trace, 100 MHz bandwidth, general purpose Oscilloscope. Vertical mode switching enables any combination of five channels to be displayed simultaneously. Channels 1 (CHI) and 2 (CH2) each has ten calibrated deflection factors from 5 millivolts/division to 5 volts/division selected in a 1-2-5 sequence. The horizontal deflection system has calibrated sweep rates of 20 nanoseconds/division to 0.5 seconds/ division in 23 steps. A ten times magnifier expands each horizontal sweep to maximum of 2 nanoseconds/division. An X-Y display mode is provided via an X-Y selector switch. 1.2 Features The features of the C0S6100M 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. x 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 MŒ ±1%, 20 pF ±2 pF, allowing the use of 10x Probes. (6) 5-channel simultaneous display: The C0S6100M 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.) (8) Stable alternate triggering function: 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) 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. (10) 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. (11) Alternate sweep: The A sweep and the delayed sweep can be viewed simultaneously in the alternate mode. (12) Linear focus: Once the beam focus is adjusted, it is automatically maintained in this state regardless of changes in intensity. (13) Multiple-channel X-Y operation: By using the CH3-HOR channel as the X-axis input and all other channels as the Y-axis inputs, up to four channels of X-Y operation can be viewed.
