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.

The HD RANGER 2 field strength meters offer compatibility with the VCM / ACM modulation schemes

HD RANGER 2 field strength meters offer compatibility with the latest 16-APSK / 32-APSK constellation setups and VCM / ACM modulation schemes which are often used in satellite radio links, mainly for news gathering and video contribution purposes.

Experience why the HD RANGER 2 is the industry reference

The HD RANGER field strength meters come packed with professional functions that turn them into much more than a TV analyser. Beyond the basic all-purpose testing functions, the latest firmware versions enable users to perform advanced measurements directly over the spectrum trace and detect and manage the next-gen 4K video codec.

PROMAX supports the deployment of Ultra HD in France

The Future TV Days 2015 exhibition organised this week by TF1 has been the opportunity for the French satellite broadcaster FRANSAT to present a new distribution solution for Ultra HD channels based on the PROMAX CompactMax headend.

COMPACT MAX: The reliable and economical solution to watch satellite TV via DTT

In those buildings where several signal types are received (Satellite, Terrerstrial, Cable, Encoded) headend modules are expensive and complex. PROMAX had designed the CompactMax transmodulator that converts Satellite TV to DTT in a quick and cost-efficient way. Satellite channels are delivered in DTT format and there is no need of Satellite TV decoders or additional wiring.
