The Agilent / Keysight 8340B is a synthesized sweeper providing precise microwave signal generation across 10 MHz to 26.5 GHz. This instrument delivers 0.1 Hz frequency resolution, tuning in under 10 ms, and output power spanning -127 dBm to +13 dBm with ±1.0 dB accuracy. Phase noise performance reaches -100 dBc/Hz at 10 kHz offset across the frequency range, while spurious signals remain below -60 dBc. The unit supports AM, FM, and pulse modulation with flexible sweep modes—frequency, power, and list—enabling rapid characterization of microwave components and systems.
