Product Description

Keysight N8481A

Certified Premium Used at BRL Test

  • EEPROM to store cal factors eliminates manual entry
  • Wide frequency range from 10 MHz to 18 GHz
  • Wide dynamic range from -35 dBm to +20 dBm
  • Best-in-class power linearity of less than 1%, excellent SWR of mismatch uncertainty and highly accurate power repeatability
  • Accurate calibration and traceability to US National Institute of Standards and Technology (NIST)
  • SCPI codes compatible with 8480 series (option CFT)

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)
