Front Panel Menu Reference

This section describes all the hardkeys and softkeys on your power meter.
The hardkey descriptions are in alphabetical order. The softkey
descriptions are in the order they appear in the menus. Diagrammatical
hardkeys are described at the end of this section.
The hardkeys can be separated into three categories, those which affect:
• the system setup, for example the HP-IB address.
• the currently selected window setup, for example the
measurement units.
• the channel setup, for example channel offsets.
dBm/W
The softkey menu structured to this hardkey 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 hardkey 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 2-20 for further information.
