An Immunity-Scan is, very much lika a Multi-Scan measurement, only we measure immunity and not emission.

  • The signal generator (SG) and the Error Detection Device (EDD) is reset
  • Basic settings are transferred to the SG and the EDD
  • The Scanner moves to the first measuring position.
  • The lowest frequency and amplitude is sent to the SG.
  • Wait for a while (dwell time) to let the DUT react.
  • Measure DUT failure using the EDD and the Detection sequence.
  • If the DUT does not fail we increase the amplitude and measure again for DUT failure until the DUT fails or we reach the highest amplitude setting.
  • Store frequency and amplitude data.
  • Set the next frequency and redo from (5) until we have measured all frequencies.
  • The Scanner moves to the next measuring position.
  • Steps 4 to 10 are repeated until all measuring positions are measured.
  • The Scanner moves to its starting position.
