TV Explorer (Prodig 5A)
The Promax TV Explorer (Prodig 5A) 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.
Overview
The Promax TV Explorer (Prodig 5A) automatically searches for channels available in any type of network and displays the quality of each signal. It does not require any preliminary information to scan & measure signals. When a signal is found, it will display all the available information about the available channels such as standard, modulation type, symbol rate, etc.
|
The Promax TV Explorer's compact and rugged construction makes it ideal for field use. A 5" color LCD screen shows all measurement results and can also display the picture of analogue and digital channels found by the Explorer. The Explorer includes a spectrum analyzer function, where the user controls how the signal is displayed. It can also give the parameters and display any signals in DVB-S, DVB-C and DVB-T formats. You can download the TV Explorer PDF brochure for more information.Tele-Satellite International published two very articles on the TV Explorer (first and second in PDF format). You can also watch Promax videos available on YouTube! 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.

Easy to use
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.
Auto Identification
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.
Signal Measurement
All measures about a particular channel / transponder can be seen in one screen. The display adapts itself to the type of signal being measured:
 |
Analogue measurement:
|
 |
DVB-S (QPSK) & DVB-T (COFDM) measurement:
|
 |
DVB-C (QAM) measurement:
|
Spectrum Display
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. |
Signal Demodulation
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:

Portability
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.
Antenna Installation
|
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 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.Battery
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.
Light Sensor
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.
