Output Power

Set the power level out of the FieldFox to High, Low, or manually set power
level to a value between High and Low.
Generally, the high power setting is used when measuring passive, high-loss
devices to place the signal farther from the noise floor. However, for devices
that are sensitive to high power levels such as amplifiers, use the Low power
setting.
For best measurement accuracy, use the Manual power setting at -15 dBm.
After calibration, the power level can be decreased for amplifiers, or increased
for higher dynamic range.
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.

trigger will revert to Internal trigger. This includes turning on a CAL that
requires forward and reverse sweeps or displaying multiple parameters that
would require forward and reverse sweeps.

with 2-port cal." will be displayed and point mode trigger will revert to
Internal trigger.

Trig Slope
—Positive Sweep is initiated by the rising edge of signal at about 1.7 V.
—Negative Sweep is initiated by the falling edge of signal at about 1.0 V.

Output Power

— High Sets output power to the maximum achievable power at all
displayed frequencies. Output power is NOT FLAT across the
displayed FieldFox frequency span. Please see
