Setting the Range

that can be set are those of the Agilent E- Series power sensors and N8480
Series power sensors (excluding Option CFT) . With an Agilent E- Series
power sensor or N8480 Series power sensor (excluding Option CFT), the
range can be set either automatically or manually. Use autoranging when
you are not sure of the power level you will be measuring. There are two
manual settings either “LOWER” or “UPPER”. The lower range is more
sensitive than the higher range. “LOWER” covers the range of –70 dBm to
–13.5 dBm. “UPPER” covers the range of –14.5 dBm to +20 dBm. The
default is “AUTO”.
