MegaZoom Concepts
MegaZoom technology combines the advantages of conventional
deep-memory digital oscilloscopes with the responsiveness and update
rate of traditional analog oscilloscopes. Conventional deep-memory
digital oscilloscopes are known for their ability to capture long time
intervals while still maintaining high sample rates. MegaZoom
technology keeps the deep-memory advantages, without the usual
deep-memory disadvantages of an unresponsive user interface (while
panning and zooming through the data) and poor signal update rate.
MegaZoom technology incorporates a multi-processor architecture in
the signal data path between the oscilloscope probe and the oscilloscope
display. This yields an instrument that responds instantly to pan and
zoom controls while exploring the acquired data. MegaZoom technology
combines update rate, instant control response, and deep-memory
innovations to allow you to capture long time periods with high sample
rates, and instantly zoom in on the signal details of interest either while
stopped or running. Deep-memory, front-panel responsiveness and
display update rate are combined into one oscilloscope, with no need for
a special mode or memory depth selection.
