Acquire the Signal
When and Why to Turn On MagniVu
For MSO4000 Series only, MagniVu allows you to have higher resolution to accurately determine edge placement. This helps
you to make precise timing measurements on digital edges. You can see up to 32 times more detail than with 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 fi nd 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 page 185, Viewing Digital Channels.)
