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 their own result images with the database images, users 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. The first requirement is to know what the pure signal looks like before determining the type of interference.
The ‘Signal Guide’ from Narda Safety Test Solutions is a collection of time characteristics, spectrums and spectrograms. The result images and descriptions can be accessed by selecting categories such as RF Services or Modulation Types, or by displaying 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.
