Power Meter Mode - Agilent Technologies FieldFox N9923A Quick Reference Manual

Power Meter Mode – Option 302
Power Meter measurements are made using the
Agilent U2000 Series USB Power Sensors.
Damage levels are:
 +25 dBm (320 mW) average
 +33 dBm peak (2 W) <10μs
 +5V
Use an Attenuator between the DUT and the power
sensor when measuring power levels that are higher
than +20 dBm. The attenuator value can be subtracted
from the measurement using Offset as follows:
Select Offset
 Press Scale / Amptd then
 Then Offset Val
meter display is offset. A positive value
compensates for a component with loss, such as an
attenuator.
Zeroing
The Agilent USB Power Sensors perform internal
zeroing automatically. Internal zeroing does NOT
require that the power source be turned OFF.
Perform external zeroing when measuring power
levels below -30 dBm. During external zeroing, the
power source MUST either be turned OFF or the
power sensor be disconnected from the DUT.
