Merogram and Spectrogram

21 Gennaio 2014.

Both Merogram and spectrogram functions of PROMAX field strength meters have been developed to allow for an early identification of intermittent and sporadic problems that may only happen in limited periods of time.

Merogram: DTT channel quality monitoring

The Merogram (patented function) is a useful function designed to help in the detection of DVB-T, DVB-T2, DVB-C or DVB-C2 channel reception problems.

This function displays in the field strength meter screen a graphical representation of the MER level for each carrier of the locked signal, which is superimposed over time. During the Merogram function, maximum and minimum of some parameters and the time when they are reached are stored. This tool is especially useful for detecting sporadic problems over time.

Spectrogram: Easy signal spectrum waveform monitoring

The Spectrogram function of field strength meter RANGERNeo 2 shows a graphical representation of the spectrum superimposed over time of a channel or frequency selected by the user. During the Spectrogram, maximum and minimum of several measures and time are registered. This tool is especially useful to analyse the behaviour of a spectrum over time, because sporadic and indeterminate anomalies can be detected.
