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.
