Pre-compliance EMC measurements
We measure during development, put the results into technical context and work on the causes with you – so that EMC topics do not surface shortly before the design freeze.

The situation
Testing EMC too late costs time and forces expensive changes
In many projects, EMC is only tested at the end. By then the boards are manufactured, the enclosure tooling is ordered and dates have been promised – every change reaches deep into the product.
If a limit is exceeded at that stage, only expensive routes remain: retrofitted filters, additional shielding, layout changes or a postponed market launch. Often parts get swapped on suspicion, because the cause is unclear.
What separates pre-compliance measurements from an accredited test – in purpose, not in diligence – is explained in What is pre-compliance testing?
How we work
Measure, analyse the cause, develop a measure, re-measure
Four steps, repeated as often as development requires. Consulting is part of the work, not a separate add-on.
- 01
Measure
Measurement in the test centre that fits, with documented setup and operating states.
- 02
Analyse the cause
Narrow the interference source down to the board, a cable, a connector or an opening in the enclosure.
- 03
Develop a measure
Derive concrete measures and estimate the effort and the expected effect.
- 04
Re-measure
Verify and document the effect under identical conditions.
After the measurement
Your results
We agree scope and depth of assessment per project – depending on product, target market and development stage. The following elements are the rule.
Measured values and documentation
- documented measured values per frequency, operating state and test setup
- traceable documentation of the test setup
Technical assessment
- technical assessment against the relevant limits
- notes on critical frequency ranges and operating states
Next steps
- concrete optimisation recommendations
- optional proposal for a re-measurement under comparable conditions
Preparation
What we need before the appointment
The more complete this information is, the more focused the measurement day will be. Whatever is missing, we clarify together beforehand.
- Type of product and development stage: concept sample, prototype or pre-series
- Dimensions and power supply of the device under test
- Target market and requirements you already know about
- Anomalies you have already noticed during development
- The operating states you want to have measured
- Necessary peripherals, loads and counterparts
- Existing measurement reports, if available
Where we measure
Depending on the question, we measure in the fully anechoic chamber in Harbke or in the shielded chamber in Meine.
Shielded chamber, Meine
Complementary shielded test environment
- single-phase, up to 16 A
- up to 60 V, 10 A
