Keysight N8481S, N8487S RF Balance Thermocouple Power Sensors

Keysight N848xS Series Balance Thermocouple Power Sensors

The Keysight N848xS series are balance thermocouple power sensors which are intended to be used as measurement standards for RF power. They are suitable for use in a microcalorimeter-based primary measurement standard and as a secondary or reference measurement standard. The balance thermocouple power sensors offer a broad frequency range DC up to 18 or 50 GHz, high maximum input power of +20 dBm, fast measurement speed/settling time as well as ease of maintenance.

• DC to 18 or 50 GHz operating frequency range.
• -35...+20 dBm power measurement range.
• RF to DC thermoelectric substitution measurement method.
• Less than 0.2 reflection coefficient magnitude across the operating frequency range at 50 Ω reference impedance.
• DC resistance range from 50 Ω to 2 kΩ.
