Beschreibung
The Tektronix RM561A Oscilloscope is essentially an indicator unit with provision for two plug-in units. The plug-in unit in the right-hand opening controls the horizontal (X-axis) deflection, and the plug-in unit in the left-hand opening controls the vertical (Y-axis) deflection. The plug-in units can be selected from any of the Tektronix ‚2‘ Series or ‚3‘ Series groups to provide the desired oscilloscope performance.
