The Agilent/Keysight E9300A is an average power sensor designed for precise measurements across broad frequency and dynamic ranges. It interfaces with compatible Agilent/Keysight power meters to characterize both continuous wave and modulated signals, including complex digital formats such as W-CDMA, CDMA (IS-95), TDMA, and OFDM. The sensor employs dual independent measurement paths that automatically select between high and low power ranges, with hysteresis-based switching to prevent chatter near the transition point. Internal EEPROM stores calibration factors, linearity data, and temperature compensation coefficients to ensure measurement traceability to NIST standards.
