6 Using N8480 Series Power Sensors
148 N1913/1914A EPM Series Power Meters User’s Guide
Introduction
The N8480 Series power sensors are replacement for the 8480 Series power
sensors (excluding the D- model sensors) with build- in
E lectrically E rasable
P rogrammable R ead- O nly M emory ( 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).

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

and so 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 Agilent N8480 Series
power sensors for specification and calibration information.
