The MARKER menu allows placing a marker, which shows the input power level at the specified frequency.
MARKER and POWER IN BAND cannot be activated both at the same time.
Tapping the PEAK button turns on and off the automatic search for the highest input power level in the displayed
frequency range, and places the MARKER there. Tapping the CENTER TO MARKER button changes the CENTER frequency to the
current MARKER frequency (while preserving SPAN, if possible), i.e. centers the graph on the MARKER.
The current MARKER frequency is displayed in white. The color of the keypad buttons shows which numbers can be
entered at the current digit position to obtain a valid parameter value – the numbers on the
green
buttons can be entered, the
numbers on the
red
buttons cannot be entered. If the currently entered value is valid, it is displayed in green (also OK button is
green). If the value is not valid, it is displayed in
red
(also OK button is
red
). To confirm a valid value, tap the OK button or tap
the parameter’s box.
To exit the SPAN menu and return to the main screen, tap BACK.
