The Keysight / Agilent / HP 8567A is an affordable high-performance spectrum analyzer for bench and ATE use. It covers frequency of 10 kHz to 1.5 GHz. Multiple traces can be displayed to measure residual FM or drift, or to conduct real-time surveillance over a wide frequency range. Analyzer control settings can be saved in non-volatile memory. Complex measurement routines can be created on an external controller, stored in the analyzer's user RAM, and executed using a single custom softkey. By adding measurement accessories and options, the 8567A fits into many applications, including electromagnetic compatibility (EMC) testing, automated broadband signal surveillance, and component stimulus-response testing.
