The Promax RANGER Mini Compact Touchscreen CATV Analyzer is a multi system analyzer that can work in terrestrial, satellite and cable transmission systems. It can also be expanded to work with optical fiber.

The RANGER mini has all the functions necessary for an easy installation of any service. In addition, its intuitive menu, its adjusted weight and strength, makes it ideal for fieldwork.

The RANGER mini features a 5 in. professional grade resistive type touchscreen display with excellent brightness and superior image sharpness. It includes a case with a touch pen to make easy browsing around the menus. The instrument is powered by an internal rechargeable battery.

The RANGER mini has been designed with particular attention on making a practical and precise instrument, as well as easy to use. The touch interface allows direct access to different modes of operation and once there, it is easy to modify any parameter of the measurement.

All this makes the RANGER mini in a magnificent tool for installing and maintaining all kind of systems: Terrestrial, satellite and HFC (Hybrid Fiber Cable) / CATV. It is also very useful for testing DOCSIS data transmission systems.

In addition, the instrument provides Ethernet and USB port slots to connect to external devices, to download data and to update firmware.

DOCSIS Bonding

As part of the DOCSIS 3.0 standard multiple upstream and downstream channels can be "bonded" to be used together as one. RANGER mini includes a comprehensive channel bonding screen where information about all of them is combined with other single channel measurements such as the constellation diagram.

DOCSIS 3.1

DOCSIS 3.1 systems can use (among other things) an extended frequency range which goes up to 1500 MHz in the forward path, with a return band of up to 200 MHz. The RANGER mini RF input covers up to 2700 MHz.

Scan and Tilt

The SCAN function is probably the fastest way to check if all signals in your network are present. It displays graphically all the analog and digital channels in a selected channel plan along with their signal levels.

TILT measurements are used to identify system frequency unbalance which must be accurately compensated by field technicians.

Constellation Diagram

Constellation diagram is a simple and graphical way to identify signal impairments which impact MER and ultimately BER. These are probably the most important measurements technicians can do to assess digital QAM channel quality.

Datalogger

The datalogger function can perform various measurements including signal level and channel power, carrier/noise, BER and MER for all the channels listed in a given channel table automatically. All of this information is saved in the analyzer and it can be copied to a pen-drive or to a PC for further processing at a later stage.
