The Keysight Technologies (formerly Agilent HP) E9301H is an E-series diode power sensor designed for measuring average power across a wide dynamic range from -50 to +30 dBm over a frequency spectrum of 10 MHz to 6 GHz. It is bandwidth-independent, allowing accurate measurements of various complex modulation formats without the need to match sensor bandwidth.
