RF Synthesiser

RF Synthesiser


The Laplace Synthesisers cover both conducted and radiated RF immunity test requirements. The frequency coverage extends from 100KHz to 230MHz for conducted tests and 30MHz - 3GHz for radiated tests. They are all controlled from the users PC via a USB link, and powerful Windows software is included to enable the user to control all the parameters of the test, to monitor the test in progress, and to view the results.
