The Anritsu 68147C is a synthesized signal generator engineered for automatic test equipment (ATE) applications across 10 MHz to 20 GHz. It delivers excellent signal purity, fast output agility, and stable performance in wireless, aerospace, and military test environments. The instrument provides +17 dBm guaranteed leveled power to 20 GHz and extends down to –140 dBm with electronic attenuation, supporting both continuous wave and modulated signal generation with 0.1 Hz frequency resolution.
