Overview Of The N8480 Series Power Sensors - Keysight Technologies N8480 Series Operating And Service Manual

Overview of the N8480 Series Power Sensors

The N8480 Series power sensors are high accuracy thermocouple power
sensors that allow direct measurement of RF or microwave power through
the heating effect it has on a terminating load. All calibration data for the
N8480 Series power sensors is stored in EEPROM
the power meter when the sensor is connected. In terms of functionality
and performance, they
thermocouple power sensors.
The N8480 Series power sensors are used for measuring the average power
supplied by an RF or microwave source or a device- under- test (DUT). In
use, the power sensor is connected to the RF or microwave source and to
a compatible power meter. The N8480 Series power sensors are compatible
with the EPM Series power meters (E4418B, E4419B, N1913A, and
N1914A), EPM- P Series power meters (E4416A and E4417A), and P- Series
power meters (N1911A and N1912A) only. The N8480 Series power sensors
place a 50 W load on the RF or microwave source. The power meter
indicates the power dissipated in this load in mW or dBm.
The N8480 Series power sensors consist of four sensor model types with
respective power range:
• A- models (–35 dBm to +20 dBm)
• B- models (–5 dBm to +44 dBm)
• H- models (–15 dBm to +35 dBm)
• Waveguide- models (–35 dBm to +20 dBm)
