N8480 Series Power Sensors Operating and Service Guide
To carry out a zero and calibration cycle required by the power meter,
refer to the respective power meter’s
User’s Guide
for details of the power
sensor’s zero and calibration procedures.
For new connections and measurements below –25 dBm (applicable for
N8487A with serial number MY48700101 to MY54089999 and N8488A with
serial number MY50230001 to MY540899999 only), it is recommended to
perform the following steps.
1
Connect the power sensor to the test port.
2
Allow the power sensor to settle for at least 20 minutes with no
RF power.
3
Perform zeroing with the power sensor still connected to the test port.
Recommended Calibration Interval
Keysight Technologies recommends a one year calibration cycle for the
N8480 Series power sensors.
Temperature Sensitivity
The sensitivity of the power sensor is influenced by ambient temperature.
The sensor should be recalibrated at each change in temperature to obtain
the most accurate results. The sensor has a built- in temperature
compensation that ensures the accuracy of measurement carried out
within 0 to 55 °C, refer to
for details. For measurement below
–25 dBm, it is recommended to re- apply zero procedure when there has
been a temperature variation of more than ±5 °C since the last zeroing.
N O T E
It is recommended to perform frequent zeroing when performing measurements below
–25 dBm.
