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 conventional 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 scope probe and the scope 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 special mode or memory depth selection.
MegaZoom Technology’s Deep Memory Improves Timing Resolution
The HP MegaZoom technology used in the HP 54645A/D oscilloscopes keeps the
sampling rate at the maximum for all sweep speeds of 500
µ
s/div and faster in
Single mode, and 200
µ
s/div and faster in Run mode.
