FM radio is coming to an end? PROMAX develops new technologies for DAB and DAB+ analysis

PROMAX has a new type of demodulator for DAB and DAB+ that can be optionally installed into the RANGER Neo field strength meters so that they be equipped with the most versatile DAB/DAB+ analyzer available today. It includes an expanded frequency margin of up to 800 MHz, among other benefits over the rest of DAB analyzers of the market.

What do PON, GPON, XG-PON, 10G-EPON stand for? Which analyzers are compatible with them?

PON stands for "passive optical network" referring to the optical network composed by non-active components in all stages between the origin (local exchange) and the external sides (subscriber or clients). The others acronym (GPON, XG-PON…) corresponds to the standard transmission that travel through this physical network. In which are they different?

What do RMS and True RMS stand for? Here we explain you the differences

The TRMS instruments are much more accurate than the RMS when measuring AC current. This is why all the multimeters in PROMAX catalog have True RMS measurement capabilities.

PASS / FAIL: It may turn against you

The PASS/FAIL function is widely used in measuring instruments. Specifically talking about field strength meters it may become a great ally to check signals quickly, which turns into a double-edged sword in the hands of users if they do not know what they are doing. It is necessary to take into account certain variables that cannot be diagnosed by a simple PASS / FAIL function.

How to certify an optical fiber installation

Why the optical fibre installations must be certified? What do the regulations state? In order to test the appropriate performance of an optical fiber installation, a calibrated LASER generator and an optical power meter are used. Then, a measurement report can be generated based on the results.

What is the T2-MI signal and how to analyze it

T2-MI is a communication interface embedded into the second-generation digital terrestrial television signals (DVB-T2) received by the modulators that carry out the broadcasting itself. In fact, T2-MI stands for T2 Modulator Interface. The telecommunications networks technical managers use the T2-MI information to ensure the proper deployment of the digital terrestrial television networks.

How to fusion splice two optical fibers

In this article, we will give you a brief, easy step-by-step guide about how to make two optical fiber fusion splicing: Removing the plastic coating of the fibres, cutting the optical fibers, run the splicing in the optical fusion splicer...

What is the Link Margin measurement?

The Link Margin is a measurement that indicates how much MER a digital channel can lose before it is impossible to "lock" it. This happens when the Link Margin measurement is equal, very close or below zero. Then the decoder error corrector is not able to recover data lost at transmission. We will learn to appreciate its importance.

How to fix the interferences of coaxial wiring on mobile phone networks

Since the 4G came up we are aware about how mobile phone networks affect television coaxial cable networks. But what happens when occurs exactly the opposite, when coax networks have an impact on mobile networks? Why does this happen? And if the problem is not solved, it is subject to a sanction?
