50MHz dual channel analog oscilloscope.The 50 MHz dual-channel oscilloscope PM 3217 and PM 3217U is a compact, portable instrument, ergonomically designed to facilitate its extensive measuring capabilities. The instrument provides both a main and a delayed timebase with provision for alternate timebase displays, comprehensive triggering facilities including peak-to-peak Auto, DC coupling and automatic TV waveform display. A large 8 x 10 cm screen with illuminated internal graticule lines makes for easier viewing, and a 10 kV accelerating potential gives a high intensity trace with a well-defined spot. The wide range of applications enabled by the above features is further extended by a versatile power supply that enables the instrument to be operated from different line voltages as well as from d.c. For field operation an optional battery version is also available.
