The Anritsu 69247A Synthesized Signal Generator delivers precise RF signal generation across 0.01–20.0 GHz, with optional extension to 26.5 GHz. This instrument functions as a local oscillator replacement, component analyzer, signal simulator, and ATE system source. Output power ranges from −125 dBm to +13.0 dBm typical, with frequency resolution down to 1 kHz standard or 0.1 Hz with Option 11. The 69247A combines low phase noise (−100 dBc SSB at 10 kHz offset from 10 GHz), fast frequency switching (<40 ms to 1 kHz settling), and flexible modulation in a single platform.
