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 

Offset On Off 

  

 

Then 

Offset Val

 Enter a value by which the power 

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.   

 

Press 

Cal   5

 

 

Then 

External Zero
