Agilent/Keysight E9300H

The Keysight E9300H is an average power sensor delivering precise measurements across 10 MHz to 18 GHz with an 80 dB dynamic range. It measures average power for all modulation formats independent of signal bandwidth, eliminating the need to match sensor bandwidth to modulation type. Built-in EEPROM storage preserves calibration factors, linearity data, and temperature compensation coefficients for traceable, NIST-correlated measurements.

Technical Specifications

Frequency Range: 10 MHz to 18 GHz Power Range: −50 dBm to +30 dBm (80 dB dynamic range) Typical Power Linearity at 25 °C (after zero and calibration):

• −26 to −20 dBm: ±0.9%


• −20 to −10 dBm: ±0.8%


• −10 to 0 dBm: ±0.65%


• 0 to +10 dBm: ±0.55% Impedance Match: Typical SWR of 1.15 from 10 MHz to 18 GHz at 25 °C ±10 °C, minimizing mismatch uncertainty Connector: Precision Type-N (standard)

Key Features

• Bandwidth-independent measurement of average power across all modulation formats


• Low SWR design reduces mismatch error
