The Promax HD RANGER 2 ISDB-T features a new 7" touch screen with excellent brightness and superior image sharpness that can also be used wearing gloves. The hybrid operation of the HD RANGER 2 ISDB-T allows the equipment to be fully operated using both the touch panel and the conventional keyboard.

HD RANGER 2 features all the benefits of HD RANGER+ ISDB-T functions plus IPTV input, Common Interface (CAM) for encrypted channels, HDMI interface and TS-ASI input/output. Optical measurements and 3 GHz band extension can also be included as an option, thus converting the HD RANGER 2 in an all-purpose field strength meter. It also works with signals comforming to the ISDB-T/Tb television standards.

Selective Optical-to-RF Converter

RFoG (Radio frequency-over-Glass) is used more and more by CATV operators because it allows them to benefit from the advantages of fiber optics to compete with FTTH service providers. It is common to combine two downstream wavelengths: 1550 nm for Digital TV and 1490 nm for Data services.

TV&SAT distribution in buildings is also taking advantage of the benefits of fiber optics, thanks to the use of Optical LNB's and RF/FO converters which will presumably be extended over the next years. Having integrated optical filters, the Promax HD RANGER 2 is compatible with the latest technologies using two wavelengths simultaneously to distribute up to 2 satellites (including all 4 polarities each), in addition to the terrestrial channels.

The RF signal at the converter output can be analyzed, measured and decoded by the meter as one would usually do with any DVB or Analog TV & Satellite signal over copper wires.

Selective Optical Power Meter

The selective Promax HD-RANGER/2 OPM combined with a portable triple laser source such as PROLITE-105 (sold separately) forms a complete Optical Loss Test Set that allows you to measure fiber attenuation. This is of great interest in live FTTH/GPON installations certification or even before they are in service.

IP Input

IPTV stands for TV over IP networks. It actually means TV over any type of IP packet based distribution network. They can be referred to as LAN (Local Area Network), ethernet, computer networks, etc...

With the growth of LAN based TV distribution systems, having an IPTV input in your field strength meter becomes a handy feature.

IPTV Reception

The Promax HD-RANGER/2 allows you to receive television programs coming from IPTV networks. Those programs can be displayed on the screen together with other important service information.

Measurements on IPTV Signals

Although some concepts are similar, signal quality assessment metrics is not the same in IPTV as it is in digital TV over radio frequency. The Promax HD-RANGER/2 offers you the measurements you need to understand, identify and correct the new problems that can be found in this new type of television distribution networks.

DVB-S2 Multistream

Advanced modulation techniques allow you to aggregate several independent transport streams into one single RF carrier. Selecting a specific TS is easy with your Promax HDRANGER2 using the ISI Filtering function. This feature is available for DVB-S2, T2 and C2.

PLS - Physical Layer Scrambling

The PLS index is a number generated by the broadcaster that must be properly decoded by the customer so that demodulation is possible. The Promax HD-RANGER 2 can also work with these type of signals.

Beacon - Flyaways, SNG and VSAT

The Promax HDRANGER-2 spectrum analyzed function makes it easy for technicians working in VSAT applications to setup their satellite transmission-reception systems.

OFDM Constellation

The constellation diagram is a graphic representation of the digital symbols received over a period of time. The Promax HD-RANGER-2 has different types of constellation diagrams for the different modulation modes. DVB-T/T2, DVB-C/C2 and DVB-S/S2 constellations are available on the Promax HDRANGER/2.

8PSK and QPSK Constellation

In the case of an ideal transmission channel, free of noise and interferences, all symbols are recognized by the demodulator without mistakes. In this case, they are represented in the constellation diagram as well defined points hitting in the same area and forming a clear dot).

16, 32, 64, 128, 256 QAM Constellation

Every modulation type is represented differently. A DVB-C16QAM signal is represented on the screen by a total of 16 different zones, and a DVB-C 64QAM is represented on the screen by a total of 64 different zones and so on.

LTE Interference on SMATV Systems

The Promax HDRANGER 2 has a variety of tools that allow you to compare the signal reception quality measurements on digital TV channels with and without the LTE filter. This is very helpful to anticipate the performance improvement you should expect on your TV distribution system well before you physically make changes to the cabling to insert the LTE filter.

HDMI Interface

The Promax HDRANGER-2 includes an HDMI output to interface with other High Definition equipment. The Promax HDRANGER-2 can also be very useful to check proper operation of the client's TV while on a service call. Everything that can be seen on the meter's screen is available through the HDMI.

Transport Stream Input and Output

Having a TS-ASI input and output is an essential feature when you work with professional digital head end equipment. You can monitor and analyze streams coming from satellite receivers, transport stream players, multiplexers, etc... You can use the transport stream received by the Promax HD-RANGER2 to feed the signal to other devices as well.

Downlink and Uplink Interference

Downlink interference comes from the mobile phone base stations which are placed at fixed locations and are always on. This is not the case of Uplink interference which comes from the handheld devices and therefore it can be a lot more difficult to locate and mitigate.

Common Interface

The Promax HDRANGER2 includes a CI slot that allows interfacing with CAM modules available in the market and decoding encrypted channels. The use of encryption is widely spread among television operators so this function is very useful indeed.

Dynamic Echoes Analysis

Dynamic echoes measurement is an essential function in DVB-T, DVB-T2 and recently in DVB-C2 as well. The Promax HDRANGER 2 covers all these standards. The information about the various echoes received at the test point is displayed on a bespoke screen where data is laid down in a comprehensive way including power, delay and other channel details.

PC Connection

The USB interface in the Promax HDRANGER 2 can be used to connect it to a USB memory or to a PC computer. NetUpdate4, a free download PC software, is also available from our website. This complete application allows updating the meter's firmware, editing channel tables, processing datalogger information, etc...
