2.13.3 MASK MODE
The MASK MODE menu allows setting a file as a spectrum mask and thus visually
comparing the current spectrum curve with a saved one.
MASK MODE is not available for CUMULATIVE and MIN/MAXHOLD trace mode.
CUMULATIVE traces cannot be used as masks. The MAXHOLD trace is set as
a mask from a MIN/MAXHOLD file.
To enter the file system, tap SELECT FILE. Navigate through the files using arrows
or the slider, tap on the file to select it and then tap the SET AS MASK button. The
mask curve is displayed in
red . Tapping the RELATIVE MASK button turns on and off
centering of the mask. If the RELATIVE MASK button is active ( green ), the mask is
centered on the current CENTER frequency. If the RELATIVE MASK button is inactive,
the spectrum curve used as mask is positioned in its actual frequency range with
which it was saved. To adjust the mask vertically i.e. set a MASK OFFSET, tap the +10,
-10, +1 or -1 button that moves the mask curve by 10 or 1 decibels upwards or
downwards. To clear the MASK OFFSET, tap C.
To exit the SELECT FILE submenu, tap BACK. To exit the MASK MODE menu and
return to the TOOLS menu, tap BACK. When MASK MODE is activated, the MASK
MODE button is
green at the TOOLS menu. Tapping the MASK MODE button when it
is active disables the MASK MODE. MASK MODE is disabled by default.
