N8480 Series Power Sensors

N8480 Power Sensor

The N8480 Series power sensors are thermocouple solutions for highly accurate RF power measurements, ranging from 100 kHz to 50 GHz. These new sensors are now integrated with EEPROM capability, which simplifies calibration by removing the need to manually key in calibration factors at each frequency point.

The N8480 power sensor offers improved accuracy with excellent SWR, exceptional power linearity (<1%) and first-rate repeatability; resulting in more efficient testing and reducing manufacturing costs.

In addition, the N8480 has broadened its dynamic range by extending the lower power level down to -35dBm, providing industry’s widest dynamic range of 55 dB (single sensor solution) and 79 dB (combined sensor solution) in a thermocouple power measurement solution.

  • -35 to +20dBm (N8481/82/85/87A)
  • -15 to +35dBm (N8481/82H)
  • -5 to +44dBm (N8481/82B)

All N8480 sensors are designed to be backward compatible with the EPM (E4418B/19B), EPM-P (E4416A/17A) and P-Series (N1911A/12A) power meters to minimize re-coding efforts and investment. The N8480 sensors are not compatible with Keysight 43x, E1416A, N8262A power meters; 5314x microwave counters and E7495x base station test set. (More information)
