N8480 Series Thermocouple Power Sensors
Data Sheet
Introduction
The Keysight Technologies, Inc. N8480 Series thermocouple power sensors are amongst the most accurate
and reliable sensors, plus they include EEPROM, and extended frequency and power ranges.
Accurate, repeatable measurements
Here’s how: Excellent linearity (1% approximately) and noise specifications. The sensors’ low SWR further
enhances accuracy by minimizing mismatch uncertainty. These sensors also come with dual-range power
for greater sensitivity to fluctuating signals. With high accuracy and stability, the N8480 helps you test
confidently, faster.
Calibration-easy testing
During test, calibrating your sensor is an essential step. Minimizing the time this step takes is essential.
The N8480 sensor eliminates cumbersome keying-in of the calibration factor (CF), eliminates manual input
errors, and saves you time and effort. CF, linearity, and temperature corrections are all stored in the sensors’
EEPROM—auto-downloaded on calibration. The N8480 Series streamlines the calibration procedure making
overall testing faster and more efficient.
One sensor, WIDEST range
Pick an N8480 sensor—any one—and you’ll see how its wide dynamic range equips you for various
applications: metrology labs, radar, mobile radio, TDMA, GSM, W-CDMA, and WiMAX™, among others.
With up to 55 dBm wide dynamic range, the N8480 Series offers you the widest thermocouple sensor power
range in the industry.
System integration can be difficult, but not with the N8480
The N8480 Series sensors are backward compatible with the Keysight leading range of power meters,
including the P-Series, EPM-P Series, and EPM Series. All that’s needed is a simple firmware upgrade that’s
downloadable for free from the Website.
All SCPI codes used on the E-Series sensors are re-usable on the N8480, including most of the codes used
on the 8480 Series. When migrating code from the 8480 Series, Option CFT 1 will allow SCPI codes to
behave much like they do on the 8480 Series.
Features
–– High accuracy with excellent linearity and noise specifications
–– Wide dynamic range in a single sensor
–– Auto-download of calibration factor and corrections from EEPROM
–– Option CFT provides full-code compatibly between sensors and the 8480 Series (excluding the N8488A)
–– Broad compatibility with existing power meters: P-Series (N1911A/12A), EPM-P Series (E4416A/17A),
and EPM Series (N1913A/14A, E4418B/19B)

Option CFT is not available for the N8488A power sensor.

Specification Definitions
There are two types of product specifications:
–– Warranted specifications
–– Characteristic specifications
Warranted specifications
Warranted specifications are covered by the product warranty and apply over 0 to 55 °C,
unless otherwise noted. Warranted specifications include measurement uncertainty
calculated with 95% confidence.
Characteristic specifications
Characteristic specifications are not warranted. They describe product performance that
is useful in the application of the power sensors by giving typical, but non-warranted
performance parameters. These characteristics are shown in italics or denoted as
“typical,” “nominal” or “approximate.”
Characteristic information is representative of the product. In many cases, it may also be
supplemental to a warranted specification.
Characteristic specifications are not verified on all power sensors. The types of
characteristic specifications can be placed in two groups:
–– The first group of characteristic types describes ‘attributes’ common to all products
of a given model or option. Examples of characteristics that describe attributes
are product weight and 50‑Ω input Type-N connector. In these examples, product
weight is an approximate value and a 50‑Ω input is nominal. These two terms are
most widely used when describing a product’s attributes.
–– The second group of characteristic types describes ‘statistically’ the aggregate
performance of the population of products. These characteristics describe the
expected behavior of the population of products. They do not guarantee the
performance of any individual product. No measurement uncertainty value is
accounted for in the specification. These specifications are referred to as typical.
Conditions
The power meter and power sensor meet their specifications when:
–– Stored for a minimum of two hours at a stable temperature within the operating
temperature range and turned on for at least 30 minutes
–– The power meter and power sensor are within their recommended calibration periods
–– Used in accordance to the information provided in the power meter’s user’s guide

RH is the abbreviation for relative humidity.
Average hourly drift, at constant temperature. If there is an abrupt change of temperature, it is strongly recommended to perform zeroing or waiting for
30 minutes before taking the measurement.
The number of averages at 16 for normal mode and 32 for x2 mode, at a constant temperature, measured over one-minute interval and two standard
deviations.
The zero set, zero drift, and measurement noise specifications are tested at 50 MHz.
N/A is the abbreviation for “not applicable.”
Effects of averaging on noise
Averaging over 1 to 1024 readings is available for reducing noise. The table below
provides the measurement noise for a particular sensor with the number of averages
set at 16 (for normal mode) and 32 (for x2 mode). Use the noise multiplier, for the
appropriate mode (normal or x2) and number of averages, to determine the total
measurement noise value.
Example:
N8481A power sensor, normal mode, number of averages = 4

Performance Characteristics (continued)
Switching point
The N8480 Series power sensors (excluding Option CFT) have two measurement ranges:
a lower power range and an upper power range. The power meter automatically selects
the proper power level range. To avoid unnecessary switching when the power level is
near the switch point, switching point hysteresis has been added.
N8481A/82A/85A/87A/88A and N8486AQ/AR power sensors
This hysteresis causes the lower power range to remain selected until approximately
–0.5 dBm as the power level is increased. Above this power, the upper power range is
selected.
Likewise, the upper power range remains selected until approximately –1.5 dBm as the
signal level decreases. Below this power, the lower power range is selected.
N8481B/82B power sensors
This hysteresis causes the lower power range to remain selected until approximately
29.5 dBm as the power level is increased. Above this power, the upper power range is
selected.
Likewise, the upper power range remains selected until approximately 28.5 dBm as the
signal level decreases. Below this power, the lower power range is selected.
N8481H/82H power sensors
This hysteresis causes the lower power range to remain selected until approximately
17.5 dBm as the power level is increased. Above this power, the upper power range is
selected.
Likewise, the upper power range remains selected until approximately 16.5 dBm as the
signal level decreases. Below this power, the lower power range is selected.

Calibration factor and reflection coefficient
Calibration factor (CF) and reflection coefficient (Rho) data are unique to each sensor.
The CF corrects for the frequency response of the sensor. The Keysight EPM Series,
EPM-P Series, and P-Series power meters automatically read the CF data stored in the
sensor’s EEPROM and use it to make the corrections.
The reflection coefficient (Rho or r) relates to the SWR according to the following formula:
SWR =
1+r
1–r
Typical measurement uncertainties of the calibration factor (CF) are listed in the following
table. There is only one set of CF data used for both the high and low range of each sensor.
The typical measurement uncertainty data listed in the table is meant to help users on
the measurement uncertainty estimation. These values are only a guideline and are not to
be used in any accurate uncertainty calculations. For accurate measurement uncertainty
values, please refer to the measurement report 1 of the specific sensor.
