Condition: Used

The Keysight N1921A P-Series Wideband Power Sensor is in good working condition. It covers 50 MHz to 18 GHz with a -35 to +20 dBm dynamic range. Correction data including calibration factors, linearity, temperature, and bandwidth are stored in EEPROM. The sensor features a precision Type-N connector with a fixed cable attached.

What is typically included based on the product description:
• N1921A wideband power sensor
• Fixed sensor cable (available in 1.5 m / 3 m / 10 m lengths)

The Keysight N1921A is a P-Series Wideband Power Sensor designed for use with Keysight P-Series power meters such as the N1911A and N1912A. It is the industry's first wideband power sensor to feature internal zero and calibration, integrating a DC reference source and switching circuits directly into the sensor body. This eliminates the need for multiple connections to an external calibration source, reducing connector wear, shortening test time, and minimising measurement uncertainty.

The sensor is suited to characterising pulsed, bursty, and modulated signals across a wide range of RF and microwave applications including wireless communications, radar, and semiconductor test.
