Use magnification with the WFM displays, VECTOR displays, EYE displays, and
the Bowtie display (found in the MEAS menu).
Select a trace display.
Press and hold the MAG button to display the Magnification pop-up menu.
Select a magnification setting, such as Best View, x10, x20, x25, or x30. In
the Vector displays, the magnification is called H Gain (horizontal gain). The
available options depend on which display is active.
Once you have set up magnification parameters, you only need to press the MAG
button once to activate magnification. Press it again to remove magnification.
