N8480 Series Thermocouple Power Sensor Specifications
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 50 GHz and
have two independent power measurement range (upper and lower range).
Meanwhile, the N8480 sensors with Option CFT only measure power levels from
–30 dBm to +44 dBm (1 μW to 25.1 W) in single range. Similar 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.
