Product Description
HP E9300B / Agilent E9300B E-Series Average Power Sensor 10 MHz to 18 GHz, with Matching 30dB Attenuator
Most power sensors used for measuring average power employ either thermocouple or diode technologies.Diode based sensors frequently rely on the application of correction factors to extend their dynamic rangebeyond their square law response region, typically –70 dBm to –20 dBm.However, while this technique achieves wide dynamic range capability, it islimited to continuous wave (CW) signals outside the square law region. Modulated signals must be padded down or at low levels, with their average and peak power levels within the diode square law region, to bemeasured accurately. Accurate, average power measurement of high levelsignals carrying modulation cannot be obtained using a CW correction factor technique. Specialized modulation sensors provide accurate measurements but are bandwidth limited.
