ST-240 LNBs & Satellite receivers tester
The ST-240 is a compact, easy to use and low cost signal generator that
allows an effect verification of satellite recievers and LNB's.
* 13 v,18 V LNB power stupply test
* 22 kHz switching signal verification
* Video and audio demodulation test
* LNB verification, vertical and horizantal polarizations
TI-330
The accessory permins to check and to test the new DiSEqC switches and LNB's.
A protocol each time more required in modern installations.
The T1-330 is micropocessor controlled, making it very reliable and accurate
TI-340 DiSEqC checker
The T1-340 permins to check at any point of an installation the presence and state of DiSEqC signals.
A set of LEDS signals the presence in the coax-cable of the following signals:
- Hi/Lo - Mini DiSEqC tone
- H/V - 22 kHz
- Posiotion - 60 Hz
- Switches - 13 and/or V
NG-281/NG-282 Noise Generators
The NG-281/NG-282 noise generators are large bandwidth devices espaecially designed for application in all kinds of
televidion installations,whether terrestrial, cable or satellite distribution.
The frequency range of the NG-282 is from 950 to 2,000 MHz, and the NG-281 from 5 to 1,000 MHz.
Powered by battery or mains adapter ,they enable to user to perform measurements in combination with fields level meters or spectrum analysers in highly complex installations.
Obtaining the frequency responses of active and passive circuits, measuring impedance adaption and the relation of the detection of anomalies in transmission lines,are some of the function where NG-281/NG-282 noise generators are of great assistance.
LN-370B Low-Noise Amplifier
The LN-370B is a low-noise amplifier which enables the dynamic range of spectrum analysers and field strength
meters to be extended , in order to measure signals with very weak amplitudes.
CV-550 Sub-band Converter
The CV-550 converts sub-band channels to VHF for their measurement by TV/FM field strength meters.
TI-220 22 kHz Inserter
This small accessory, placed at the RF input of meters, permits insertion of a 22 kHz signal,
required by some LNBs to select the operation mode (band, polarisation, etc.)
PC-108 Polarisation Controller
The PC-108 is a universal magnetic polarisation controller. It is powered by the input connector without interrupting power to the LNB.
AMC/1 Master Aerial
The AMC/1 master aerial is a dipole with interchangeabke arms (in function to the band), mounted on a hand-held mast,
which, connected to fields strength meter, permits the value of the electric field intensuty at a paticular location to be found.
In order to do this, it is necessary to configure the aerial in function of the frequency,
connect it to the field strength meter, and add the corresponding correction factor to the read value.
