Laplace Instruments Products: Conducted Immunity

Conducted immunity testing covers both RF and non-RF requirements.

The RF standard is IEC61000-4-6 (see below).

The non-RF standards cover a wide range of tests, including:

  • IEC61000-4-2   ESD
  • IEC61000-4-4   Fast Transient burst (EFT)
  • IEC61000-4-5   Surge
  • IEC61000-4-8   Magnetic field (power frequency)
  • IEC61000-4-9   Magnetic field (Pulsed)
  • IEC61000-4-11   Dips and interruptions (ac)
  • IEC61000-4-29   Dips and interruptions (dc)

The ONYX16 is a fully compliant solution for the ESD test and the AXOS5 is an integrated unit with a range of options that covers the other tests.

RF compliance tests

An integrated system (the RFIC system) offers the benefits of a fully calibrated, automated and cost effective solution.

This system comprises a Synthesiser/control with an RF power amplifier, to which can be added CDNs to suit the cables to be tested.
The S46xxx range of CDNs are 'versatile'. This means that each type of CDN can be programmed to suit many cable types, thus reducing the number of different types of CDN required. Our CDNs are also available in an 'enhanced' format (the E46xxx range). The enhanced CDBs are fitted with a feedback system so that monitoring of the stress applied to the cable can be achieved in real time during a test. This improves accuracy and avoids the need for time consuming 'pre-scan' to calibrate the applied level.

The system is controlled via a USB link from any standard PC. Windows application software is included with each system.

The new AXOS5 compact immunity test system integrates several tests into one compact and integrated system.

It combines 5 kV Burst/EFT, Surge combination wave, AC/DC Dips & Interrupts, along with an integrated single-phase coupling / decoupling network into one compact test system. This allows quick and completely automated testing to the most common IEC,EN, ANSI, IEEE and UL standards.

For those not requiring the full compement of tests, the AXOS5 is available at lower cost for any one single test type, and other tests can be added at a later date as required.
