The Keysight (Agilent/HP) 8350B is a high-performance sweep oscillator mainframe designed for microwave measurements, CW signal generation, and automatic testing. Compatible with the HP 83500-series and 86200-series (via adapter) RF plug-ins, it offers a broad frequency range from 10 MHz to 40 GHz depending on the installed plug-in. It features HP-IB programmability, five independent markers, and nine save/recall registers for instrument states.
