Kikusui COR5500U series Oscilloscopes are available in eight models, with different combinations of frequency bandwidths and a digital storage function to best suit your applications. The eight modes are: COR5501U: 100MHz oscilloscope, with 20MS/s digital storage COR5500U: 100MHz oscilloscope COR5561U: 60MHz oscilloscope, with 20MS/s digital storage CORS560U: 60MHz oscilloscope COR5541U: 40MHz oscilloscope, with 20MS/s digital storage COR5540U: 40MHz oscilloscope COR5521U: 20MHz oscilloscope, with 20MS/s digital storage COR5520U: 20MHz oscilloscope This manual is applicable to Models COR5501U, COR5500U, COR5561U, and COR5560U oscilloscopes. 1.2 Features (1) Easy to operate You can easily use major functions of the oscilloscope which employs a direct knob control system. (2) Compact and light COR5500U series is very compact and light for its sophisticated functions and reliable performance. This has become feasible through dexterous use of flush-mount components. (3) CRT readout The CRT readout displays various items of information on the CRT screen, providing you with a powerful means for rapid but accurate measurements. (4) Comment display You can display comments by using this feature. If your oscilloscope has the digital storage function and operates with GPIB, the comment text you have written can be output to an HP-GL plotter via GPIB. (5) Alternate magnified sweeps This feature allows you to magnify readily any portion of the waveform you want to observe more closely. The timebase can be magnified by 5,10, or 50 times. The Alternate Magnified Sweep mode, which runs a main sweep and a magnified sweep alternately, is also available. (6) Sampling rate up to 20MS/s The maximum sampling rate is 20MS/s. Each channel has an 8bit A/D converter, allowing you to store the single-shot data from both channels simultaneously. In Single Trigger Mode, you can capture frequency components up to 5.7MHz (when Curve Interpolation is used). (7) 4k words/channel memory capacity Each channel has a 4k word memory, and resolution of 400 points per one division horizontally. The digitally stored and reproduced waveforms closely resemble the original analog ones. COR5500U series has two 4k-word Saving Memory units. The memory units are internally backed up so that the data is not destroyed even if the power is turned off. The data is maintained for a longer period. (8) Repetitive mode The COR5501U can store repetitive signals up to 100MHz and, COR5561U can store up to 60MHz in Random Sampling mode. (9) Printing screen data for HP-GL plotter If an optional GPIB Interface (IFOl-COR) is attached to your oscilloscope, waveforms and all readouts can be directly output to a GPIB plotter if it accepts HP-GL commands.
