High Res The High Res mode uses on the fly over sampling and averaging Each displayed sample point represents the average value of the samples acquired in the elementary time interval The High Res mode increases the effective vertical resolution of the oscilloscope The High Res mode reduces the signal random noise The High Resolution mode can be used even with SINGLE mode because the averaging takes place at each point displayed and not on successive waveforms acquisitions as in the Average mode 64 4 Channel SPO Digital Oscilloscopes Functional Description Functional Description IV ACQUISITION System cont d Sequence Mode In the Sequence mode the recording memory is segmented The oscilloscope captures and records a waveform Frame at each trigger event When the acquisition sequence is completed the oscilloscope displays the first 20 acquired waveform segments In this mode the waveform capture speed can reach up to 300000 waveforms sec When a trigger event occurs the oscilloscope acquires and records a waveform segment and then waits for a new trigger event The oscilloscope blind time is minimized allowing the capture of certain signal details that were not visible with other acquisition modes For a 14Mpts maximum memory depth and with all four channels activated the table below shows the maximum number of Frames according to the Time Base coefficient Time Base Sampling Current memory Maxi
