Using persistence to accumulate on-screen
points from numerous acquisitions makes it
easier to view signal changes over time. But
Analog Persistence
, with intensity grading,
makes this even easier by signifying the most
frequent signal path ‘three-dimensionally’. Here’s
how to use this unique feature to reveal the AM
modulation of a sinewave.
$SSOLFDWLRQ6HWXS
