Expert On-Site EMC and Radio Interference Testing
At EMC Technologies, our expert team provide specialist on-site services for electromagnetic interference testing. Our service is for organisations that require accurate assessment where laboratory testing is either impractical or impossible.
Our engineers carry out field-based investigations, while providing compliance support and fault diagnosis across Australia and the Asia-Pacific region.
When is On-site Testing Required?
On-site testing is typically required when equipment can’t be easily transported to a laboratory, when interference occurs only in its operational environment or where installation size or fixed infrastructure prevents conventional testing.
At EMC Technologies, we support organisations that require electromagnetic interference testing at operational sites, including facilities with large machinery, installed systems or intermittent interference issues.
Field-based testing is essential when conducting an RF site survey to understand ambient radio conditions before installation or compliance testing.
Our on-site testing services are commonly used to support:
- Large or fixed equipment that can’t be relocated
- Installed systems which require compliance verification
- Investigation of intermittent EMI issues
- Pre-compliance checks for CE mark testing on oversized devices
- In-situ evaluation prior to formal CE marking test programs
Radio Frequency (RF) Interference Investigations
We have extensive experience conducting RF interference investigations across a wide range of sectors. Our engineers routinely perform EMI survey work to identify, locate and resolve sources of electromagnetic disturbance.
Using portable, calibrated instrumentation, our team carry out detailed electromagnetic interference testing to assess emissions, immunity and real-world operating conditions. This includes narrowband frequency discrimination measurements and broadband assessment across a wide frequency range.
Typical investigations include:
- RF interference affecting critical systems
- Fault diagnosis where interference can impact performance or safety
- RF site survey activities to establish background RF conditions
- Targeted EMI survey investigations to isolate problem sources
- Support for regulatory and compliance investigations
Our Specialist Site Testing Services
Our in-situ testing team provide a comprehensive range of field-based services using portable EMC equipment and specialist measurement systems.
At EMC Technologies, our services include:
- RF site survey assessment for ambient RF environments
- Electromagnetic interference testing for emissions and immunity
- EMI survey investigations for fault identification and resolution
- RF EMF measurements for occupational and public exposure
- On-site support for CE mark testing of large equipment
- Field-based CE marking test activities where lab testing is not possible
- Portable shielded room deployment for controlled on-site testing
Our range of services allows us to support compliance, diagnostics and approvals without the need to relocate complex installations.
The Advantage of Field-Based Expertise
Field-based testing provides insights that laboratory testing alone can’t always achieve. Real-world installations can often introduce variables such as cabling routes, grounding systems, nearby transmitters and operational interactions that directly influence performance.
At EMC Technologies, our experienced engineers combine electromagnetic interference testing expertise with practical site experience to enable accurate interpretation of results and provide actionable recommendations.
This approach is particularly useful for organisations that require RF site survey data to support installation planning or EMI survey findings to resolve operational disruption.
Where required, site testing can also be used to support CE marking test programs for large or installed equipment.
Solve Your Interference Issues with a Professional Site Investigation
AT EMC Technologies, we work with clients across a wide variety of sectors to identify and resolve interference issues accurately and efficiently.
Our site testing services deliver reliable data, practical solutions and clear reporting to support compliance, fault resolution and operational performance.
FAQs about On-Site Radio Interference Testing
Can you find interference that only happens intermittently?
Yes. Our engineers conduct extended investigations to capture intermittent events and correlate them with operational conditions.
What information do I need to provide for a site survey quote?
To enable us to provide an accurate quote for a site survey we require details such as site location, equipment type, frequency range of concern and known symptoms to help us scope the RF site survey accurately.
Is on-site testing as accurate as lab testing?
On-site testing provides different insights from lab testing. While laboratory testing offers controlled conditions, field testing captures real-world behaviour, which is essential for diagnosing interference and to support CE mark testing where laboratory testing is impractical.
