The Keysight (Agilent/HP) 8900D is a digital peak power meter designed to directly display the peak power of RF pulses from 100 MHz to 18 GHz when used with the 84811A peak power sensor. Featuring a 3.5-digit digital display calibrated in watts and automated range annunciators, the 8900D is an excellent choice for production and field service applications requiring clear, unambiguous pulsed power measurements.
