OSCILLOSCOPE The new Analog-/ Digital Scope Generation from HAMEG with Autoset, Save / Recall, Readout / Cursor and RS-232 Interface Demands Solution Modern oscilloscopes must meet additional demands without neglecting the advantages The following description explains some of their predecessors. Oscilloscopes, which are user selectable between the analog and advantages of these oscilloscopes. the digital mode, are undoubtedly the most versatile displaying instruments and meet this The excellent frequency response of requirement.
