MIRA Ltd has chosen PPM’s Sentinel IIsc RF over fibre platform to support its DEF-STAN 59-411 EMC test capabilities

A number of tests detailed in DEF-STAN 59-411 specify the use of fibre for transporting RF measurements, including

The intense fields specified in the standard could potentially corrupt any measurements if they were transported over long lengths of coaxial cable. The Sentinel IIsc platform makes these measurements possible by providing EM hardened optical transmission modules. Test times are also reduced by providing easy to access pre-amplification and connection to multiple transducers.

Peter Phillips, EMC Department Manager at MIRA says “The recent purchase of a four channel, fibre optic link has increased the capability of MIRA’s nine EMC test facilities. This added benefit improves measurement accuracy and demonstrates MIRA’s commitment to supporting our customer’s defence and aerospace EMC test requirements”.

"Fibre systems have long been used in aircraft EMC clearance. DEF STAN 59-411 takes these established test methods and extends their relevance to land and sea based systems. Maintaining signal integrity is vital and fibre based systems offer an effective method of achieving this requirement" commented Phil Surman, Business Development Manager at PPM.

Test & Instrumentation Applications

The point2point and Sentinel IIsc FOL ranges provide a means of conveying RF signals in the presence of intense electrical fields. These products, in conjunction with our RF sensors/probes and measuring receivers, serve the needs of the EMC, EMP, lightning test and Tempest communities.

point2point is the ideal solution for a wide variety of data acquisition applications. It also meets the security requirements for critical TEMPEST applications. The system offers a data link which is as easy to use as an electrical cable, but with the inherent advantages of optical fibre i.e. low loss; immunity to interference; non-conductivity; low mass and small size. point2point products offer bandwidths from high accuracy DC to more than 4.2GHz.

The Sentinel IIsc Intelligent Fibre Optic Link product range allows the user to remotely select inputs, link gain, pre-amplifier, calibrate signal etc. It offers additional shielding for higher field operation. Bandwidths of up to 1GHz are available.

PPM are Manufacturers of: - RF over Fibre Solutions from DC to 4.2GHz; EMC Shielded Intelligent Fibre Optic Links; point2point Fibre Optic Links

PPM are Distributors for:
