2.7.5 Scale
The SCALE 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.
SCALE menu is only available for default units “dBm”. See
UNITS
.
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). If the input power range allows it, sliding the graph up or down modifies the MAX and
MIN values by equal amounts.
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
(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 selected parameter’ box.
To exit SCALE menu and return to the LEVEL menu, tap BACK.
