A Compact 9 kHz to 3.0 GHz Phase Coherent Triple Output Signal Generator APMS3003

The APMS3003 is a phase coherent triple-output RF signal generator with a frequency range from 9 kHz to 3.0 GHz and is ideally suited for a wide range of application, where good signal quality accurate and wide output power range is required. Good phase noise is combined with spurious and harmonic rejection. A high-stability OCXO reference provides excellent frequency accuracy and stability. THe OCXO can be phase locked to an external 10 MHz reference.
