When and why to turn on MagniVu
Tektronix MagniVu acquisition technology allows you to have higher timing
resolution so that you can more accurately determine edge placement and make
more precise timing measurements on digital edges. Using MagniVu, you can see
up to 32 times more detail than you can using normal digital channel sampling.
The MagniVu record is acquired in parallel to the main digital acquisition and is
available at any time, running or stopped. MagniVu provides an ultra high
resolution view of your data sampled at a maximum resolution of 60.6 ps for
10,000 points centered around the trigger.
NOTE. MagniVu centers itself around the trigger point. If you turn MagniVu on
while using a large record length and you are looking somewhere other than the
trigger point, then the digital signal may be off screen. In most of these cases, you
can find the digital record by looking for the digital signal in the upper overview
and panning accordingly.
NOTE.
You should turn on MagniVu when light gray shading is displayed to
indicate the uncertainty of the edge position. If the shading is not displayed, you
do not need to use MagniVu. See
Viewing digital channels on page 73.
