For example, quency class have been designed. One operates one new plug-in unit, the Display Scanner, en from dc to 30 megacycles, the second from dc ables the oscilloscopes to be used with X-Y to 15 megacycles. Both have been designed to recorders to reproduce the display on paper, operate through such environmental condi the difference in speed between oscilloscope tions as MIL vibration and shock tests, tem and recorder notwithstanding. peratures up to 50°C, humidities up to 95%, A second new horizontal plug-in is a sweep and altitudes up to 10,000 feet. delay generator which has new features for In addition to advancements in ruggedness, greater flexibility in delayed sweeping. Still the new oscilloscopes include a number of another generates intensity modulation mark electrical advancements, the most notable be ers so as to facilitate such measurements as rise ing that plug-in units have been designed for and fall times. the oscilloscopes' horizontal axis as well as the A full series of vertical plug-ins has also been vertical axis. Through this arrangement it has designed.
