What is the difference between 4K and H.265?

4K, MPEG-4, H.265… are different concepts which may cause a confusion that often paves the way to abusive commercial practices. The difference is: 4K is the definition. H.265 is the compression.

What is an OTDR and how to read its measurements

In the internal optical fiber network within a facility is relatively easy to locate the failure point. But when a broader optical network comes into play it is almost impossible to locate the street, façade, tunnel or conduction where a breakage has occurred if we don’t use an OTDR that shows up the distance between the measurement point and the fault.

How to use the IF simulator

By using an IF simulator it is possible to certify the performance of an RF distribution installation via coaxial cable. Let’s see four methods, to check that the signal delivered to each outlet features the best quality possible using PROMAX IF simulators and field strength meters.

Four FREE new features for the RANGER Neo analyzers – just by updating the firmware

Top range RANGER Neo TV and Spectrum analyzers from PROMAX include these utilities as default. You can upload and download files from the analyzer’s internal memory as well as creating and editing channel plans. You can generate PDF reports in a single click. You can even remotely control the equipment: It is possible to literally use it from the other side of the world. All of this, from an internal webserver, thus it is run conveniently from the web browser under any operating system

Problems in DTT reception? The weirdest origins of television interferences

Even the most skilled professionals sometimes are unable to easily find the origin of an interference that is causing the picture to pixelate/blur, or the DTT signal to be interrupted or even unable to be received. In this article we are listing the most surreal known sources of problems in digital terrestrial television reception.

Optical fiber connector types: An easy guide

The acronyms SC, LC, FC and ST refer to the most common types of optical connectors in FTTH applications and data networks. As for the PC/UPC/APC terminology, it refers to the type of polishing applied to the optical terminal (ferrule) which makes possible laser light pulses to cross through two optical fibers.

5G interferences measurement equipment

PROMAX analyzers are compatibles with the Second Digital Dividend (5G). No need to update the firmware! HD RANGER and RANGER Neo field strength meters are factory ready for the 5G and they can be used to guarantee the 700 MHz band is not interfering the regular TV broadcasting reception.

Tool for Drive Test and Benchmarking: KML Generator

Engineering services and telecommunications operators running Drive Test measurements, Network optimizations, Walk test and Service quality analysis can now take profit of the ability of PROMAX analyzers to perform signal coverage analysis of television broadcasting centers. Now, with the KML Generator utility, there are much more options to generate 3D signal coverage maps, Microsoft Excel spreadsheets and CSV files to export them to databases or third party applications.

It’s all about 24/7/365 monitoring

We have developed application specific functions such as Network Delay, Shoulder Attenuation or Coverage Analysis which include a great degree of automation. The way these functions are laid down on the analyzer is so intuitive that users really appreciate the effort. Technology 50 years in the making!

Cheap TV spectrum analyzers: The 6 flaws nobody tells you

An inexpensive field strength meter with the same features than a professional device, at a fraction of the price? Such suggestive promises are suspicious: The technology found at PROMAX TV analyzers is often not found in cheap equipment. The installer will decide whether it is worth to renounce it…
