- 10 MHz to 18 GHz frequency response
- Wide dynamic range from -15 dBm to +35 dBm
- Built-in EEPROM allows calibration factors to be loaded automatically to eliminate manual input errors (not available with option CFT)
- High accuracy with excellent power linearity and repeatability
- Compatible with EPM (N1913A/14A, E4418B/19B), EPM-P (E4416A/17A), P-Series (N1911A/12A) power meters
- SCPI code compatibility with 8480 series (with option CFT). Option CFT is available as a replacement of legacy 8480 Series power sensors intended for cal factor manual entry and SCPI compatibility. Option CFT is not compatible with 43x and other obsolete power meters.
- N8481H/100 has Type-N (m) connector
Keysight's new Thermocouple Power Sensor is a replacement product for legacy 8480 power sensors. They provide more accurate power measurements with excellent power linearity and repeatability.
The Keysight N8481H is enhanced with an EEPROM which automatically loads the calibration factors whenever the sensor is connected to the power meter.
Option CFT is available as a drop in replacement for legacy 8480 Series Power Sensors by maintaining the manual calibration factor entry and SCPI compatibility.
Compatible with Keysight EPM (E4418B/19B), EPM-P (E4416A/17A) and P-series (N1911A/12A) power meters family only (free firmware upgrade may be required).
Not compatible with older 400 Series power meters.
