(default setting at -15 dBm) Set output power to an arbitrary
value, FLAT across the displayed FieldFox frequency span. If flattened
power can NOT be achieved, a warning message and beep occurs. To
achieve a flattened output power, reduce the power level or stop
frequency.

Port Extensions
Port extensions allow you to electrically move the calibration reference plane
on either port 1 or port 2 after you have performed a calibration.
Why use Port Extensions
Use port extensions if you are unable to perform a calibration directly at your
device because the location is not accessible. Perform a calibration at a
convenient place, then use port extensions to compensate for the time delay
(phase shift) to the desired reference plane. On the FieldFox, port extensions
does not compensate for the loss of the additional electrical length, nor any
mismatch errors beyond the calibration reference plane.
Also use port extensions if you have already performed a calibration, and then
decide that you need to add a length of transmission line in the measurement
configuration. Use port extensions to “tell” the FieldFox that you have added
the length to a specific port.
