The Keysight 8990B Peak Power Analyzer is a high-performance instrument for precise measurement and analysis of peak power in pulsed RF and microwave signals. It delivers 15 pre-defined pulse characterization parameters and advanced automated measurements across a 50 MHz to 40 GHz frequency range. With measurement accuracy of 0.2 dB, dynamic range from -35 dBm to +20 dBm (CW) and -25 dBm to +20 dBm (pulse), and capture lengths up to 1 second, the 8990B excels in radar, wireless communication, and electronic warfare applications. The instrument features a 15-inch XGA color touchscreen, four total channels (two RF input and two video input), and advanced triggering capabilities for synchronization of complex pulsed signals. Sampling rates reach 100 MSa/s real-time, 1 GSa/s with ETS enabled, and 20 GSa/s. Video bandwidth supports 30 MHz for single-shot measurements and 160 MHz for repetitive signals. System rise/fall time is 5 ns with compatible wideband power sensors at frequencies ≥ 500 MHz.
