New RF Analyser for enhanced QC

Primarily for more stringent EMC pre-compliance testing (the reason why our products carry the CE mark), our latest aquisition will also help us find any hidden gremlins so future designs could perform even better.

Capable of finding spurious noise, oscillations and ringing other tests cannot uncover (using H and E field close coupled probes), this new Radio Frequency Spectrum Analyser covers a bandwidth of 9kHz - 1.5GHz.



Obviously you'll not hear at most of those frequencies, but RF emissions between equipment - air borne, or via the mains, or interconnects, can seriously affect performance.

We're already in front with immunity on sensitive inputs like moving coil, and one day we hope tonearm manufacturers will catch up - poor shielding above 30MHz!!!

So the next time you hear RF/EMI, don't automatically blame us.

Very nice! How do you test for rf susceptiblity?
I have a problem with radio cab interference ( I do use some very old equipment !!)

Testing is relatively easy - finding the solution is the hard part.

Immunity is the same as detecting emissions in that an emissive product will often also pick up to the same degree.

Finding the magnetic and electric fields in pre-compliance is done with close coupled probes. Actual compliance testing uses uber-equipment with massive aerials and powerful RF amplifiers and receivers - it is outside the scope of most manufacturers so is subbed out.

Another way of testing immunity in pre-compliance is to use the tracking generator output, and observing the outcome.
