The R5223 Rackmount Digitizing Oscilloscope has a real time bandwidth of 10MHz. It is capable of displaying real time and stored waveforms simultaneously (four real time waveforms and four stored waveforms, if dual channel amplifier units are used); the real time waveforms need not be related to the stored waveforms. The unit accepts most 5000 Series plug-ins. Pretrigger Stored X versus Y Display Roll Mode X-Y Plotter Output with Pen Lift
