The PM 3262 Portable h.f. oscilloscope enables the measurement of signals at a sensitivity of 5 mV/DIV over an extensive bandwidth of 100 MHz (35 MHz at 2 mV/DIV). The oscilloscope is provided with many integrated circuits, which guarantee very stable operation and reduce the number of adjusting points. As an aid to checking and adjusting, testpoints have been included at appropriate positions around the circuit. 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. Additionally features of the PM 3262 are the 3rd channel TRIG VIEW and ALTernate TB facilities. TRIG VIEW enables the display of the trigger signal (internal or external applied) via a 3rd channel by pushbutton selection. ALT. TB offers the instrument user a simultaneous display of the signal on the two time scales provided by the main time-base and by the delayed time-base. The PM 3262 oscilloscope features a tapless power supply that covers two voltage ranges, 100 V to 127 V and 220 V to 240 V by means of a changeover link, thus obviating the need for continuous adjustment to the local mains voltage. All these features make the oscilloscope suitable for a wide range of applications.
