2.13.3 MASK MODE

The MASK MODE menu allows setting a file as a spectrum mask and thus visually
comparing the currently displayed spectrum curve with another 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 the files using arrows or the
slider, tap on the file to select it and then tap the SET AS MASK button (to exit the
SELECT FILE submenu without selecting a mask, tap BACK). This selected mask
curve is put on graph and it 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. The vertical position of mask – the MASK OFFSET –
can be adjusted upwards or downwards in 1 dB steps by using the buttons. To quickly
set the MASK OFFSET to 0, tap CLEAR OFFSET. MASK OFFSET is 0 by default i.e. the
vertical position of the curve used for mask is as it was when the file was saved.
To exit the MASK MODE menu and return to the TOOLS menu, tap BACK. When
MASK MODE is activated, the MASK MODE button is
Tapping the MASK MODE button when it is active disables the MASK MODE. MASK
MODE is disabled by default.
