When two windows are displayed and this key is pressed, the single window
displayed is the one which was previously highlighted with the shadowed
box. On the two window display, the measurement setup menus work on the
window which is shadowed.

4 This field displays the units of measurement either dBm, dB, Watts, or %.
5 This window is configured to show an analog meter which displays the
measurement result and the meter scaling.
6 This field displays the number of pages in the current softkey menu. For
example, “1 of 2” indicates that there are two pages of softkeys and you are
on the first page. Pressing
moves you to page “2 of 2”.

meter is initially switched on, the “Contrast” menu is displayed and if you
press
“Zero/Cal” is displayed.

limits set. If the measurement is within the limits, this field is empty. If the
measurement result is less than the minimum limit set, “Undr Lmt” is
displayed. If the measurement result is more than the maximum limit set,
“Over Lmt” is displayed. Refer to

14 The information in this field is displayed on two lines and depends on the
combination of sensor type, sensor calibration table and frequency
dependent offset table that are currently selected.
Table 1- 1 shows all
the possible combinations for the two lines of the display. Find the
table entry which matches your display and use the reference number
in the left- hand column to look up
Table 1- 2 for the combination of
