3.3.4.- Spectrum (short cut button )
If this menu is chosen, the meter passes straight to the spectrum analyzer mode. In this mode
you can see the signal spectrum according to the selected span and the tuned frequency. The
lower part of the screen (under the spectrum) is used to display the parameters, measurements,
etc. The menu texts are hidden by default, so that it is easier to see the spectrum properly.
When you need to access the menus, simply press the Clear/Menu button or any of the
, or buttons.
If an analogue measurement is selected, the central part of the spectrum will display a dotted
yellow line, and if a digital measurement is selected, this line does not appear and instead there
are two dotted yellow lines at an equal distance from the spectrum’s central line. The separation
between these lines indicates the channel bandwidth that is selected at that moment.
It is worth noting that, with this meter, you can see any frequency between 5 and 2150 MHz
without interruptions .
