Using the Spectrum Analyzer
Defining the Fixed Mask’s Limits
1. Set the Edit Mask field to the limit you want to edit (Upper or
Lower).
You might want to set the Mask Beep field to Off while you are
defining the mask.
2. Set the Mask Type field to Fix.
3. Set the #Pts field to the number of points you want defined by the
mask. You can define up to 15 points. The starting point is always
the left graticule on the display, and the end point is always the right
graticule on the display.
To define a straight-line mask, set the number of points to 1. The
default mask is a straight line at the top of the display.
4. Set the EditPt field to the point you want to define.
5. Set the Lvl and Freq fields to the frequency and level you want for
the point you chose in the EditPoint field.
In Figure 4-27 the frequency and level settings for each point are as
follows:
