Table 1-3 Power Range In Range Setting - Keysight Technologies N8480 Series Operating And Service Manual

1 Introduction
For B-models power sensors, the calibration factor data is valid only when the sensor is
N O T E
used with the supplied attenuator.

Table 1-3 Power range in range setting

The N8480 Series power sensors (excluding Option CFT) measure power
levels from –35 dBm to +44 dBm (316 nW to 25.1 W), at frequencies from
100 kHz to 67 GHz and have two independent power measurement range
(upper and lower range).
Meanwhile, the N8480 sensors with Option CFT (except for N8488A) only
measure power levels from –30 dBm to +44 dBm (1 µW to 25.1 W) in
single range. Similiar to the E- Series power sensors, the N8480 Series
power sensors are also equipped with EEPROM to store sensor's
characteristics such as model number, serial number, linearity, temperature
compensation, calibration factor, and so forth.
This feature ensures the correct calibration data is applied by any
compatible power meter connected with N8480 Series power sensor, and
to ensure the accuracy of the measurements.
