Front Panel Menu Reference
This section describes all the keys and softkeys on your power meter. The key
descriptions are in alphabetical order. The softkey descriptions are in the
order they appear in the menus. Diagrammatical keys are described at the end
of this section.
The keys can be separated into three categories, those which affect:
• the system setup, for example the GPIB address.
• the currently selected window setup, for example the measurement units.
• the channel setup, for example channel offsets.
The softkey menu structured to this key affects the currently selected window.
Press
to select the upper or lower measurement window on the power
meter’s display. The window which is selected is highlighted by a shadowed
box and the set up you create is implemented in this window.
Press this key to access the “dBm/Watts” menu which allows you to select the
measurement units. These can either be logarithmic (dBm or dB) or linear
(Watt or %). The default is logarithmic. The text on some softkeys may appear
grayed out. This indicates that they are not a relevant unit of measurement in
the currently selected window. Refer to
“Setting the Units of
Measurement” on page 59 for further information.
