РусскийSpectrum Analyzers which can now include Advanced DAB+ measurements
The new Advanced DAB option for RANGER Neo spectrum analyzers allows professional users to do DAB signal quality measurements and it includes many functions which are normally available in higher cost products only such as ETI recording, constellation diagram or echoes analysis.
ETI recording
ETI stands for Ensemble Transport Interface and it may be described as the equivalent to the Transport Stream for DAB. It is possible to record ETI on the analyzer so that it can then be copied to an external device for further analysis.
Dynamic echoes analysis
DAB can also be operated in a Single Frequency Network (SFN) and therefore the dynamic echoes analysis becomes a useful function to have.
DAB constellation diagram
DAB uses DQPSK modulation and so its constellation diagram shows a cloud of dots clustered around four points.
Measurements + Audio decoding
Besides its advanced functionalities, the analyzer can also measure all the basic quality parameters and decode the audio.
Slideshow
It is a slowly refreshed sequence of still frames containing information about the songs being played or traffic advisories. Slideshow is displayed in different menus on the analyzer along with other information
