Информация:
                                    The Tektronix 2235 Oscilloscope is a rugged, lightweight,
dual-channel, 100-MHz instrument that features a bright,
sharply defined trace on an 80- by 100-mm cathode-ray tube
(crt). Its vertical system provides calibrated deflection
factors from 2 mV per division to 5 V per division.
Trigger circuits enable stable triggering over the full
bandwidth of the vertical system. The horizontal system
provides calibrated sweep speeds from 0.5 s per division to
50 ns per division along with delayed-sweep features for
accurate relative-time measurements. A X10 magnifier extends
the maximum sweep speed to 5 ns per division.
