EMC Troubleshooting and Consultancy
Here are some examples of past troubleshooting successes . . .
UPS (Uninterruptible Power Supply) emissions example
The radiated emissions from this UPS (left) where traced to the design and layout of its microcontroller. Our client then re-engineered the microcontroller circuit as instructed by RadioCAD, with a resulting dramatic reduction in emissions (right).
DSL Router UHF emissions example
The UHF radiated emissions from this DSL router (left) where traced to patch-resonances due to the layout of the PCB 3V3 power-plane. Our client then re-layed the PCB under RadioCAD’s supervision. This resulted in greatly reduced processor clock harmonic emissions (right) and a compliant test result.
Payphone emissions example
This internet payphone had a problem with VHF emission from its power supply.
Telephone immunity example
A PCB re-work executed by Tim Jarvis (before forming RadioCAD) dramatically improves the EN55024 radiated immunity (annex A) of this telephone product.
