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.
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 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.
There are two types of product 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 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
