The Agilent/Keysight 8673A is a synthesized signal generator delivering precise RF and microwave signal generation from 2 GHz to 26 GHz. Built on indirect synthesis with YIG-tuned oscillator phase-locked to a 10 MHz quartz reference, it provides frequency stability better than 5 × 10⁻⁷ per day and exceptionally flat output across the full operating range. The instrument supports amplitude, frequency, and pulse modulation simultaneously, with output power continuously variable from +1 dBm to −120 dBm and 0.1 dB resolution.
