Laplace Instruments Products: Radiated immunity

A range of products which can provide all you need for compliant RF immunity testing to IEC61000-4-3. These items can be used separately, but when ordered as a complete system, they provide a complete integrated turn-key system. See under Immunity kits for complete integrated solutions

The range includes RF signal generators (Synthesisers) specifically designed to meet this immunity standard, and so they include auto-frequency stepping, the required modulation and, in particular, the automatic control of field intensity to the pre-set level. Each synthesiser is fitted with a USB interface and shipped complete with Windows-based PC software. All control and monitoring functions are provided via the software.

Power amplifiers to cover the full range from 30MHz to 3GHz are available, capable of delivering over 10V/m in our test cells. These power amplifiers are designed for reliability with good tolerance of overload and impedance mis-match.

The Test cells are an enhanced development of the TEM cell, featuring excellent field uniformity, compact size and built-in field sensor. All Laplacells are shipped ready calibrated to 3GHz for both emissions measurements and immunity tests.

Finally, the LETIS (Laplace EMC Test Integration System) is a switching unit which automates the interconnections with the power amplifiers, thus significantly increasing productivity when testing to above 1GHz.
