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).

[a] Recommended for pulse signals measurement with period of more than one second.
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.
