Recognize Radio Interference At A Glance

Narda Safety Test Solutions is releasing its private  Signal Guide” for use free of charge. This database contains typical measurement result  images for many RF signals, which can be considered as the “fingerprints” of the different signals. By comparing your own result images with the database images, you can distinguish the pure signals from interference and impairments.

Radio and TV, analog and digital, second, third and fourth generation mobile telecoms, emergency services communications, WLAN, industrial control signals – all of these services share frequency bands that overlap to a greater or lesser degree, and can sometimes impair each other or may be subject to unintentional or even intentional interference. You first of all need to know what the pure signal looks like before you can determine the type of interference.

The “Signal Guide” from Narda Safety Test Solutions is a collection of time characteristics, spectrums and spectrograms. You can access the result images and descriptions by selecting categories such as “RF Services” or “Modulation Types”, or display the result images in a gallery view for comparing with an unknown signal. There is also an annex that details how the result images were obtained.

The “Signal Guide” can be accessed under http://signals.narda-sts.com/
