    Part Number or Numbers


    The Laplace Synthesizers cover both conducted and radiated RF immunity test requirements. The frequency coverage extends from 100KHz to 230MHz for conducted tests and 30MHz – 6GHz 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.


    Key Points

    • • Creates the signal to be applied to the product
    • • Controls the intensity of that signal
    • • Monitors the condition of the EUT
    • • Acts as the interface between a PC and the test
    • • Includes PC (Windows) software to enable very simple operation


    Software Details

    The RFSynth software will run under any version of Windows from XP to Win10. It allows the following parameters to be set:

    • • Start frequency
    • • Stop frequency
    • • Frequency step (%)
    • • Stress level (V/m)
    • • Modulation (AM and pulsed)
    • • Dwell time
    • • EUT monitoring (ignore/stop/continue)
    • • EUT prompt output


    It includes facilities to load calibration data for the test cell, field probe or CDN as appropriate.

    Outputs include:

    • • Display of target and actual stress level vs. frequency
    • • EUT monitor
    • • System status
    • • Hard copy via Windows printers
    • • Results file storage to disk and subsequent retrieval
