WebPulsed FMCW Chirp Signal. The SynthHD line of RF signal generators from Windfreak Technologies can perform a pulsed FMCW chirp. This is done by first setting up an internally generated FM chirp (ramp). Deviation and rate are easily controlled in the FM tab of the supplied GUI. Webmeasurements in FMCW systems is the chirp ramp linearity. Having the full analog chain integrated on a monolithic microwave integrated circuit not only decreases design-to-design variations, but also helps increase overall measurement linearity, since it is possible to perform effective monitoring and calibration over age and temperature.
