The Anritsu 68285B is a synthesized signal generator delivering precise RF performance across 0.5 to 60.0 GHz. Built for demanding test environments, it combines low phase noise with wide dynamic range and analog modulation support. Fast switching times—under 1 ms for power-only changes and under 20 ms with attenuator shifts—enable rapid measurement sequences. Flexible sweep modes (step, manual, and analog) with phase-locked frequency steps from 1 kHz (0.1 Hz with Option 11) to full range support complex signal profiling. Step sweep accommodates 1 to 10,000 steps with dwell times from 1 ms to 99 seconds. Sweep switching completes in <15 ms + 1 ms per GHz step size or 130 dB with attenuator engaged.
