Acquire the Signal
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 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 108, Viewing Digital Channels.)

Quick Tips
If you think you need more timing resolution, turn on MagniVu to increase the resolution.
MagniVu is always acquired. If the oscilloscope is in a stopped state, you can turn on MagniVu and still get the resolution
without taking another acquisition.
The serial bus features do not use data acquired in MagniVu mode.
