Automotive EMC standards map for suppliers

An automotive component can pass its product-standard tests and still be rejected because the OEM specification calls for different levels, operating modes, har…

How to test shielded commercial enclosures

A shielded enclosure can look mechanically sound and still leak badly through one untreated seam, cable penetration or poorly bonded door contact. The test setu…

Automotive EMC pre-compliance kit for early debug

A single spectrum analyser is not an automotive EMC kit. Without the correct coupling networks, probes, antennas, amplifiers and controlled test geometry, it ca…

What a medical EMC pre-compliance lab should provide

A medical EMC lab can own the right instruments and still deliver poor pre-compliance evidence if the support equipment, EUT configuration and test records are…

How to brief a lab on standards scope

A laboratory cannot resolve an undefined standards scope by measurement. If the product, ports, operating modes and acceptance criteria are ambiguous, even tech…

UKCA marking and EMC: what evidence you need

An EMC test report does not become valid UKCA evidence simply because the product passed. The report, product configuration, applicable legislation, standards a…

Conducted RF immunity: how it is set up

A conducted RF immunity test can produce a perfectly orderly sweep while applying the wrong disturbance to the equipment under test. The usual cause is not the…

How to use a spectrum analyser to find radiated emissions sources

A spectrum analyser peak tells you where to look in frequency. It does not tell you whether the source is a clock edge, a switch-mode converter, a cable common-…

How to use a spectrogram for emissions investigations

A conventional emissions trace shows amplitude against frequency at one moment. A spectrogram exposes what happened between sweeps, often revealing the switchin…

EMC case studies that show the value of pre-compliance

A product can pass every bench functional test and still enter formal EMC testing with a cable, enclosure seam or power converter acting as an efficient RF coup…

How to read an EMC test report

A pass statement can be misleading if the wrong operating mode, cable arrangement or limit was used. The result only has meaning when the measured data and test…

EMC reporting for internal management

An EMC plot may contain thousands of valid measurement points and still tell management almost nothing about programme risk.Effective EMC reporting translates t…
