MARKER
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.
The frequency value can be entered with precision 0.01 MHz (10 kHz) by using the
“.” on keypad. To input a value with decimal digits, first enter the full MHz’s, then tap
the “.” button and enter the rest of the digits. Until the value is confirmed, the digits
after the point are displayed larger. If there are no digits displayed after the point, it
means that they are zeroes.
