Usa tv explorer ii spectrum analyzer (prodig 6B)
Proud to serve Canada, the USA & Caribbean since 1997
The Promax US TV Explorer II incorporates the latest satellite and terrestrial standards for the North American market! It has been designed for the installation, maintenance and surveillance of terrestrial, satellite and cable TV systems. This is perhaps the easiest to use spectrum analyzer on the market today with such an advanced set of features.
The TV EXPLORER II incorporate a transflective 6.5" colour LCD with a 16:9 aspect ratio.
The new transflective technology combines the advantages of the transmissive and reflective displays. The transmissive ones are those illuminated from behind the screen, with good vision in the darkness. The reflective ones use the reflection of the external light in the back of the display.
The result is an stunning vision in darkness and by the direct sunlight. The big 6.5 panoramic colour screen allows to extend the area to display the measurements and make readings easier. With the 16:9 aspect ratio the instrument can test any television signal independently of the receiv- er available.
The temperature range for the LCD is extended from 80 C to -40 C allowing its use in very extreme conditions away from the operating limits of other components.
The Promax Explorer's compact and rugged construction makes it ideal for field use. Its 6.5" color LCD screen shows all measurement results and can also display the picture of analogue and digital channels found by the Explorer.
This instrument is compatible with the new DVB-S2 format in QPSK and 8PSK modulation and it can analyzer off-air digital broadcasting (8VSB encapsulating standard of HDTV programming) as well as digital cable (QAM Annex-B).
New: All our Promax spectrum analyzers sold in the North American market come pre-loaded with the latest North American Ku-Band transponder maps of FSS and DBS satellites from 129 W, all the way to 61.5 W.
Built for the North American market!
The Prodig 6B was built for the North American market. This model features off-air HD digital (8VSB), cable digital (US QAM), DVB-S and DirecTV (DSS) digital measurement capability!
The constellation diagram is a graphic representation (called I-Q) of the digital symbols received over a period of time.
There are different types of constellation diagrams for the different modulation modes. With the TV EXPLORER II it is possible to display constellations for DVB-T/H, DVB-C, DVB-S and DVB-S2 signals.
In case of an ideal transmission channel, free of noise and interferences, all symbols are recognised 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.
Noise and impairments cause the demodulator to not always read the symbols correctly. In this case the hits disperse and create different shapes that at the end will allow to determine at a glance the type of noisein the signal.
Every modulation type is represented differently. A DVB-C 16QAM 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.
The constellation shows in different colours the densityof hits and includes zooming and scrolling possibilities and also a clear button to clean the picture. QAM 256 constellation.
The Promax TV Explorer is easy to use. Most functions can be accessed within the touch of a single key and these functions can then be controlled via the push dial and the arrow-keys. There are no complicated sub menus to navigate to get where you want...
Example: Hit the S/T button to switch between Satellite and Terrestrial or the D/A button to switch between Digital and Analog.
First of its kind, the TV Explorer also includes an Auto-Identification and an Explore key to search for information about a particular channel/frequency or to scan all bands to search for signals.
The TV Explorer is designed for use in terrestrial, satellite and cable-tv environments in both digital and analogue.
By hitting the Explore key, the instrument will search for any type of signal available and display its parameters such as Standard (Pal / Secam / NTSC), modulation type (QAM / QPSK / COFDM), transponder parameters (Symbol Rate, FEC) and channel parameters (PIDs).
Once transponders and channels are identified, the Explorer creates a registry of all the available channels for easy navigation of the entire network by the installer. Sessions can be stored and recalled at any time, to save time and organize your work.
You can also search for specific signals by manually entering the channel parameters.
All measures about a particular channel / transponder can be seen in one screen. The display adapts itself to the type of signal being measured:
Power, SER, VBER, MER, C/N, Noise Margin
Power, BER, MER, C/N, Noise Margin
Power, CBER, VBER, MER, C/N, Noise Margin
Power, CBER, MER, C/N, PER and LBER
To give the installer absolute control over his work, the Promax TV Explorer is also a powerful spectrum analyzer. This function is easy to use and allows the installer to control key parameters such as resolution, sensitivity and sweep time.
The Promax TV Explorer comes with several user-selectable color models or "skins". There are a number of possible combinations between colors and lines. Skins can help to improve the display in different light conditions and can make the user feel more comfortable with the instrument.
The 'UP-DOWN' arrows set the reference level.
Hit the 'UP' arrow and the reference level is increased by 10 dB.
Hit the "DOWN" arrow and the reference level is reduced by 10 dB.
If you are locked on a digital satellite, cable or terrestrial signal, the Promax TV Explorer will display the channel (provided it is not scrambled) and the following information when the Demodulate key is pressed:
* Channel number and channel plan
* Type of signal (DVB-T / C / S)
The Promax TV Explorer is small and rugged. It weights less than 2Kg (5Lb) including the battery, which makes it ideal for installers that must climb ladders and carry lots of equipment on the job.
The Promax TV Explorer comes complete with a carrying bag which allows you to strap it around your waist or shoulder and protects it from shocks and the elements.
The Promax TV Explorer has an "Easy antenna alignment" function which give a very fast spectrum display, ideal to locate hard to find satellite signals. Once the signal is found, you may peak your antenna using the same spectrum display or you can concentrate on the signal bar located on the right side of the screen.
The Promax TV Explorer allows you to control all types antennas and LNBs (13V/18V switching for polarity selection, 22Khz tone, DiSEqC control, etc.).
The Promax TV Explorer uses a high performance Lithium-ion battery. This batteries can provide a Max. operational time of over 4 hours. The battery can be charged in 2 to 3 hours and does not suffer from memory related problems common with Ni-Cad instruments.
A battery charge indicator ( ) lets you know when it's time to plug the instrument in the A/C for extended use or re-charge the battery.
The Promax TV Explorer would not be complete with another unique feature: a light sensor.
In addition to its extra-bright LCD display (320 candles / square cm), the Promax TV Explorer includes a light sensor that can automatically adjust the contrast and brightness of the screen.
This is not only useful to always get optimal visibility of the screen, but it can also extend the battery life of your instrument.
