The Agilent/Keysight 8340A is a synthesized sweeper delivering precise RF and microwave signal generation from 10 MHz to 26.5 GHz. This instrument combines synthesizer and broadband sweep capabilities, enabling both manual and automatic test system integration. Fast frequency switching, low phase noise, and flexible modulation support make it ideal for communication equipment development and microwave subsystem characterization.
