Acquiring Waveforms
TDS5000 Series User Manual
3-37
Fast Acquisitions mode increases the waveform capture rate to up to 100,000
waveforms per second, updating the waveform array many times between
displays. This very fast capture rate greatly increases the probability that runts,
glitches, and other infrequent events will accumulate in waveform memory. The
oscilloscope then updates the display at the normal display rate. You can control
the waveform intensity using adjustable or automatic brightness (refer to
page 3--40 for more information).
Fast Acquisitions mode adds intensity or gray scale information to each point in
the waveform array like an analog oscilloscope. The waveform array is a two
dimensional array of display pixels. Display pixel values are incremented each
time they are written by a waveform acquisition.
