LEVEL
The LEVEL menu allows selecting the MAX (highest limit of the vertical axis) and
MIN (lowest limit of the vertical axis) values of the displayed input power range in
dBm, and an input power level OFFSET value (e.g. if an external attenuator is being
used) in decibels (dB).
While at the SCALE menu, tapping the upper part of the graph decreases the
displayed input power range (zooms in) and tapping the lower part of the graph
increases the displayed input power range (zooms out). Sliding the graph up or
down modifies the MAX and MIN values by equal amounts (if there is input
power range available).
The currently selected parameter (MAX/ MIN/ OFFSET) is displayed in white. To
select a different parameter, tap on it once. 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
(and OK button is
green
). If the value is not valid, it is displayed in
red
(and OK
button is
red
). To confirm a valid value, tap the OK button or tap the selected
parameter.
To exit SCALE menu and return to the LEVEL menu, tap BACK.
