6 Using N8480 Series Power Sensors

Introduction

The N8480 Series power sensors are replacement for the 8480 Series power
sensors (excluding the D-model sensors) with build-in Electrically Erasable
Programmable Read-Only Memory (EEPROM)
The N8480 Series power sensors are used for measuring the average power
supplied by RF or microwave source or a device-under-test (DUT). The N8480
Series power sensors place a 50 Ω 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).

excluding Option CFT
[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
–30 dBm to +20 dBm (1 µW to 100 mW) 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
forth. However, the calibration factor table stored in EEPROM is not applicable for
N8480 Series power sensors with Option CFT, and require that you use default
calibration tables or manually enter the required correction factors. Likewise, they
cannot be used to make peak or time gated measurements.
Please refer to the documentation supplied with your Keysight N8480 Series
power sensors for specification and calibration information.
