The PM 3260 Portable oscilloscope enables the measurement of signals at a high sensitivity (6 mV/DIV) over a large bandwidth (120 MHz). The oscilloscope is provided with many thin-film circuits which guarantee a very stable operation and reduce the number of adjusting points. There is a wide choice of display possibilities, such as one channel, two channels alternately or chopped, two channels added, with normal and inverted positions for both input signals, and a main and delayed time-base.
