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 DFT)

of the power sensor followed by a calibration operation.
4 Connect the power sensor to the USB port of N932xC. The
analyzer will recognize the power sensor automatically.
To prevent damage to your sensor, do not exceed the power levels below.
C A U T I O N
U2000/1/2A +25 dBm (320 mW) average, 20 VDC
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.
Press Meas Setup > Disp Range to set the display range of the
7
measurement. when it is set to On, the display range will be
adjusted automatically according to the signal power dynamic
range. When it is set to Off, press Top and Bottom to set the display
range manually.
