The Keysight E9327A is a wide dynamic range power sensor for precise peak and average power measurements across RF and microwave frequencies. Engineered for use with EPM-P and P-Series power meters, it delivers ±0.2% per dB accuracy and supports time-gated measurements essential for pulsed and modulated signal analysis. The sensor features dual measurement modes—Normal Mode for peak, average, and time-related measurements, and Average Only Mode optimized for low-level signal characterization. Its 5 MHz video bandwidth with selectable bandwidth settings (High, Medium, Low, or OFF) enables dynamic range optimization for peak power acquisition in applications including W-CDMA, E-CDMA, and cdma2000 systems. All calibration factors, linearity, temperature, and bandwidth corrections are stored in EEPROM and automatically downloaded to the meter upon connection.
