Wideband signal generators, measurement devices, methods of signal generation, and methods of signal analysis.

A signal generator comprising a clock generator comprising a first direct digital synthesizer (DDS) configured to produce a clock signal based on a clock source signal, and a clock divider in communication with the clock generator, the clock divider comprising a second DDS, wherein the clock divider is configured to produce a divided signal based on (1) the clock signal and (2) a control signal indicating a divide ratio; and a plurality of selectable filters in communication with the clock divider, the plurality of selectable filters being configured to produce a filtered signal based on the divided signal, wherein a selection among the plurality of selectable filters is based on the divide ratio.
