Using N8480 Series Power Sensors

Introduction

The N8480 Series power sensors is a replacement for the 8480 Series
power sensors (excluding the D- model sensors) with build- in Electrically
Erasable Programmable Read- Only Memory
The N8480 Series power sensors is used for measuring the average power
supplied by RF or microwave source or a device- under- test (DUT). The
N8480 Series power sensors places a 50 ohm load on the RF or microwave
source. The power meter indicates the power dissipated in this load in W
or dBm.
The N8480 sensors (excluding Option CFT) measure power levels from
–35 dBm to +20 dBm (316 nW to 100 mW), at frequencies from 10 MHz to
33 GHz and have two independent power measurement path (upper and
lower range).

Meanwhile, the N8480 sensors with Option CFT only measure power levels
from –35 dBm to +20 dBm (1 µW to 100 mW) 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,
