The 83752B sweeper brings outstanding synthesized performance for general purpose benchtop, swept test or scalar applications. This sweeper provides superior accuracy and stability while maintaining the speed of an analog source. Fully synthesized CW, stepped and ramp sweep modes are available in broadband and narrowband operation. The synthesis capability is particularly useful for the characterization of narrowband devices, in which the frequency instabilities of open-loop sources become most apparent.
