Measuring the electric field strength with the HD RANGER analyser

The tool "Field Strength Meter" or “FSM” measures the electric field strength of signals in the radio spectrum bands supported by the HD RANGER. Use this tool to detect electromagnetic interference caused by poorly shielded satellite installations or faulty LNB.

HD RANGER: field strength meter supporting EWBS

The EWBS signal (Emergency Warning Broadcast System) is a system for warning and information that is implemented in analogue and digital broadcasting. In an emergency, devices compatible with this system automatically turn on and emit an audible warning. With an HD RANGER field strength meter EWBS signal can be checked.

IPTV test and measurement with the HD RANGER 2

The HD RANGER 2 field strength meter provides measurements to understand, identify and fix the new problems that are emerging in multicast television networks over IP (IPTV), which are widely used in hotels and other large television networks. The metric of quality parameters in IPTV at the last stage of transmission is of great help during installation and maintenance of these networks.

Automatic task planner: The HD RANGER analyser working anywhere, anytime by its own

Sometimes it is difficult to find out the source of a signal interference because it only appears at certain times of the day when may be impossible to take measurements. In these cases it is useful to schedule the field strength meter to auto-power on, take measurements or screenshots and store them in its internal memory.

Signal coverage GPS option

Adding this option to the HD RANGER field strength meters can record different types of measurements and add information about the time they are recorded and GPS location coordinates. The data can be overlayed on 3D a map using Google Earth.

The five golden rules to choose your next field strength meter

If you have not already done so, you are probably thinking about renewing your old field strength meter. PROMAX wants to help you. We have collected the five basic rules to make the best out of your investment.

HD RANGER 2 : Transport Stream Recording in the new update

The new software update for the HD RANGER 2 field strength meter (release 15) includes the Transport Stream Recording. This tool records real-time transport stream received by any of its inputs. Then, the recording can be played on the field meter as if it was a live signal.

The HD RANGER Lite, now with LTE measurement

From now on, the new manufactured HD RANGER Lite meters include this tool and for the meters already in operation this tool can be added by downloading the latest update at the PROMAX website. This is the same tool that already have the HD RANGER meters in the upper range of the same series.

The HD RANGER meters ready for the Digital Dividend (LTE)

PROMAX has prepared a special report about LTE. In this article we explain, step by step, how to check LTE interferences over communal antenna installations using any field strength meter of the HD RANGER series

HD RANGER: The High Fidelity sound reaches radio with the DAB+ standard

A new DAB/DAB+ measurement option is now available, in addition to the already ones available to upgrade the HD RANGER 2 and HD RANGER+ field strength meters. With this option they become one of the few analysers capable of measuring such digital radio signals.
