Using Fast Acquisitions
Unlike digital storage oscilloscopes (DSOs) that have long dead times between acquisitions, Digital Phosphor
Oscilloscopes (DPOs) are capable of acquiring waveforms at rates comparable to analog oscilloscopes.
Fast Acquisitions mode reduces the dead time between waveform acquisitions that occur in normal acquisition
mode. This enables Fast Acquisitions mode to capture and display transient events, such as glitches or runt
pulses, often missed during longer dead times that are a part of normal acquisition in a D SO.
FastAcq continuously overlays the
acquired information into a three -di-
mensional database that is updated on
the display 30 time s per second. For
each pixel in the display, the intensity
(or color) of the pixel is proportional
to the number of actual samples that
the pixel represents.
