• Before measuring low level signals—for example, 10 dB
above the lowest specified power for your power sensor.
Calibrating the power meter every time you cycle the power
on and off.
In most situations, you can press Zero to complete the two
steps (zero and cal) together.
Follow the steps below to make a basic average power
measurement.
Press Preset. (With Preset Type of Factory)
1
Press Mode > Power Meter to access the power meter mode.
2
Zero and calibrate the meter. Press Zero to make a Zero

operation of the power sensor followed by a calibration
operation.

Connect the power sensor to the USB port of N9322C. The
analyzer will recognize the power sensor automatically.
To prevent damage to your sensor, do not exceed the power levels below.
U2000/1/2A +25 dBm (320 mW) average, 20 VDC
+33 dBm (2 W) peak, <10 μs
For more information on the maximum power of U2000 series power
sensors, please refer to the Operating and Service Guide of Keysight
U2000 Series USB Power Sensors.
5
Connect the external attenuation, if required, with the power
sensor used.
6
Connect the analyzer to the base station. Connect the power
sensor to the signal to be measured. A typical BTS
connection is after the output of the power amplifier and
duplexer. The connection requires a cable and two Type- N
barrel connectors, in addition to the power sensor and
external attenuator.
