15 MHz Dual-trace oscilloscope
Информация
The 15 MHz portable dual-trace Oscilloscope PM 3226 is a
compact, lightweight instrument featuring simplicity of
operation, for a wide range of use in servicing, research
and educational applications.
Other features include provision for chopped or alternate
display of Y signals, automatic triggering, mains triggering
and triggering on the line and frame sync pulses of a
television signal.
The cathode-ray tube displays a useful screen area
calibrated into 8x10 divisions by an external graticule. All
circuits are fully transistorized and mounted on
printed-circuit boards for ease of maintenance.
The straight-forward design and layout combines simple
operation with a high degree of reliability.
