How to deploy WiFi networks and solve WiFi problems

There is a large variety of “WiFi analyzer” applications available for mobile phones but they are not real WiFi analyzers because they do not have a real spectrum analyzer to cover the physical layer and in second term because they see the WiFi environment through the ‘eyes’ of the mobile device WiFi radio transceiver. In order to develop a wireless network you need a true spectrum analyser to, for example, discover non WiFi interference.

RANGER Neo: A new breed of TV spectrum analyzers

The RANGERNeo is a new breed of multifunction TV, Satellite and WIFI analyser, intended to help installers not only to make their classic installation work easier but also to deal with the many challenges brought about by the wireless world and the new video delivery platforms.

Discovering the hidden metadata in the television signal with TS Analyser, the free tool from PROMAX

TS Analyser can carry out a depth analysis of the information of any DVB, ISDB-T/ARIB and ATSC digital television broadcast Transport Stream. It benefits from the algorithms of Transport Stream analysis used by the field strength meters RANGER Neo and HD RANGER.

Create your own 3D signal coverage map with your PROMAX field strength meter

It is easy to represent over a 3D map the measurements of a signal coverage analysis taken using a PROMAX HD RANGER analyser. With the free app KML Generator you can draw several graphs with different options and styles.

What is shoulder attenuation and how to measure it

Due mainly to nonlinearities in the power amplifiers the output RF signal contains unwanted band limit and out of band components, the shape of which has given rise to the term “shoulder”, that tend to compromise the compliance with the mask limits. Measuring shoulder is easier using PROMAX analysers.

Automatic shoulder attenuation measurement available for HD RANGER 2 TV Analyser

The shoulder attenuation measurement is one of the required measurements at the 8 VSB / ATSC broadcast system air interface. The HD RANGER 2 ATSC is now able to perform this measurement automatically and display it along with other relevant data such as pilot carrier amplitude, MER, VBER, etc.

HD RANGER 3 field Strength Meter and TV Analyser: The first with HEVC worldwide

Digital terrestrial television is at the dawn of a new transformation with the adoption of H.265 HEVC for the DVB-T2 HD digital terrestrial television. HD RANGER 3 is the first Field Strength meter and TV Analyser of its kind to offer HEVC signal demodulation compatible with this new broadcast signals now on air.

HD RANGER spectrum analyser tricks

Most professionals using field strength meters value the spectrum analyser function as one of the basic tools to locate interfering signals in their installations. Indeed, the HD RANGER field strength meters have a high spec spectrum analyzer far beyond a basic tool, thanks to its great scan speed and resolution as well as its many advanced characteristics.

How to measure LTE level with any HD RANGER field strength meter

All PROMAX HD RANGER field strength meters can be used to evaluate and eliminate LTE interferences on television reception. In addition, more advanced models (HD RANGER 2 and HD RANGER +) have one built-in LTE filter to simulate a real filter over television reception when there are LTE signals (4G mobile).

IP killed the RF star? HD RANGER 2. Functions that make a difference

Trying to draw a parallel with the famous song by The Buggles Video Killed the Radio Star we may say that RF is in danger because of the growing number of IP based TV delivery solutions. We are now introducing a new set of features in our field strength meters to help them expand their capabilities to work both in the RF and IP worlds.
