The 8663A is a powerful tool for evaluating satellite systems and their components. By substituting the 8663A as one of the local oscillators in a system, you can be confident that noise contribution is reduced to a minimum. Besides low noise, other features add to the 8663A’s desirability for local oscillator applications. High output power allows it to directly drive high level mixers commonly found in low noise systems. Excellent long-term frequency stability maintains carrier accuracy over time while its high frequency resolution can be used to tune out small doppler frequency offsets. Finally, the fast switching speed can be utilized for systems that employ frequency hop techniques for data security.
