MEMORY HiCORDER MR8847 A Anomaly simulation testing 4 ch 4 ch waveform voltage Reproduce and output the observed anomalous waveforms without modification. When resolving problems observed output measurement during research or development, you can reproduce such problems for effecient testing. You can also output waveforms that you created yourself for testing and measure the results at the same time. - Page 8 Acquiring data with triggers, and post-acquisition searching Adjust levels while displaying waveforms The MR8847A includes a search function for finding abnormal waveforms within all of the acquired data. You can use this function to search for anomalies after data has been acquired, when it is too difficult to set triggers because it is not possible to predict what types of anomalies might be observed.
