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…

Signal analyzers to install Maritime Internet. How does the Internet work in the sea?

Most boats mount motorized satellite antennas that are constantly aligned with the telecommunications satellites. Through these satellite dishes, all kinds of telecommunications are sent and received: Internet, telephony, television and data. RANGER Neo TV and Spectrum analyzers are perfect for field work because they are shock protected and they feature more than four hours of battery operation time.

How to locate pirate radio and TV stations with PROMAX solutions

PROMAX designs several monitoring and spectrum surveillance systems. The government authorities in charge of the surveillance of the radio-electric spectrum can use the PROWATCH instruments to detect and locate the pirate and irregular broadcast stations of radio and TV.

How to perform a perfect fusion splicing of two optical fibres

In this video tutorial we are demonstrating how to fusion splice two optical fibers with the ultra thin fusion splicer model PROLITE-42. After this, you will learn how to check the connection for losses. We will use a PROLITE-105 calibrated light source and a PROLITE-67 selective power meter.

Unveiling the DOCSIS 3.1 technology

DOCSIS 3.1 brings a good number of new technologies to the table which put together become the essence of this new powerful CATV standard. Here you will find these innovative developments as well as their related jargon explained below. DOCSIS 3.1 extends the Upstream band up to 192 Mhz and the Downstream band up to 1.2 Ghz (optionally up to 1.8 Ghz) with the objective of increasing network capacity.

The power measurement of a digital channel differs from its vertical scale in the spectrum analyzer. Why?

The power of a digital channel is calculated using algorithms that evaluate the received energy through its entire bandwidth. The result of these calculations will differ from the vertical scale of the graph depending on the bandwidth of the signal that is being measured. These values will be more different as the bandwidth increases. How is this measurement calculated? How are we doing at PROMAX to guarantee and improve its accuracy?

How to check coaxial wiring at facilities

Coaxial wiring in new buildings (with no headend equipment installed has to be checked using a pilot carrier generator connected to the headend and a field strength meter certifying the reception levels in each outlet. For those facilities with installations in operation, each section can be checked in the same way, disconnecting and testing one section at a time.
