Condition: For parts or not working — Untested. No returns.

This listing comprises a Keysight N8482A thermocouple power sensor paired with its matching 30 dB N-type attenuator, sold together as found. The N8482A covers 100 kHz to 6 GHz with a dynamic range of -35 dBm to +20 dBm and features EEPROM-based calibration factor storage. The sensor carries the CFT option, providing SCPI compatibility with the legacy 8480 Series.

Included in the sale:
• N8482A thermocouple power sensor
• 30 dB attenuator (matching)

Active options:
• Option CFT — cal factor manual entry and SCPI compatibility with 8480 Series power meters

The Keysight N8482B is part of the N8480 Series of thermocouple power sensors, designed as modern replacements for the legacy 8480 Series. The N8482B incorporates a built-in EEPROM that automatically stores and downloads calibration factors, linearity corrections, and temperature compensation data to the power meter upon connection, eliminating the need for manual cal factor entry and reducing measurement setup time.

The B-model sensors include an integrated high-power attenuator, extending the dynamic range to handle signals up to +44 dBm (25 W average). The N8482B is suited to applications in metrology laboratories, radar, mobile radio, TDMA, GSM, W-CDMA, and WiMAX testing environments.
