Power Level settings in this mode will NOT change Power Level settings in
other modes. To help prevent damage to your DUT, use caution when
changing modes with your DUT connected to the FieldFox test ports.
Nominal here means: a general, descriptive term or design parameter. It is
not tested and not covered by the product warranty.
The Nominal Output displayed on the bottom right side of the display
indicates a range of low and high power values. Your actual measured
output power could be a little lower or a little higher.
If you have the USB power sensor feature (Option 302) you can measure
the actual output power for your measurement. Refer to “Supported Power
Sensors” on page 13-3.
