Control Fields for Analog Measurements
Marker To
These two fields position the spectrum analyzer’s marker as follows:
• Peak moves the marker to the highest peak and enters the location
in the Position field.
• Next Peak moves the marker to the next peak to the right and
enters the location in the Position field.
• Center Freq changes the center frequency value to match the
current position of the marker.
• Ref Level changes the reference level setting to match the current
position of the marker.

Mask Beep
When the signal exceeds the limits set by the spectrum analyzer mask,
the FAIL indicator is displayed along with an audible tone (beep). You
can use this field to turn on (or off) the beep.
This field is displayed only when the spectrum analyzers mask is
displayed (Display field on Mask controls menu set to UpperOnly,
LowerOnly, or Both.)

Mask Type
This field selects the type of spectrum analyzer mask.
• Fix sets the mask to absolute limits defined in the #Pts, EditPoint,
Lvl, and Freq fields. When using fixed limits a change in the center
frequency or level may cause the mask to move beyond the viewable
area of the screen.
• Rel sets the mask relative to the center frequency and reference
level defined in the Center Freq and Ref Lvl fields on the spectrum
analyzer’s Main controls menu. The mask remains displayed even
though the center frequency or reference level are changed.
For more information, see “Using the Spectrum Analyzer Mask” on
page 115.
