THE DETAILS SET THE DIFFERENCE
ST-240 Satellite receiver & LNB tester
The ST-240 is a compact, easy to use and low cost signal generator that allows an efficient verification of
satellite receivers and LNB's in two different operating modes. Both modes require the ST-240 to be connected
to the satellite receiver which will be tuned to a determined frequency.
In the first operating mode the tuned frequency will always be the same and will allow the satellite receiver
test through the visualisation of some black and white bars on the television set that must be
previously connected to the satellite receiver. In the second operating mode the ST-240 radiates signals
directly in the satellite band. The satellite receiver will be tuned to a different frequency depending on the
type of LNB used and will show a set of black and white bars different to the previous ones that will be
displayed only when the LNB aperture is faced to the ST-240 front panel.
In addition to the black and white bar patterns the ST-240 generates a 7.02 MHz audio carrier.
Moreover it indicates whether the LNB supply voltage is correct or not and detects the 22 kHz switching
signal.
TI-330 Inserter
This accessory permits to check and to test the new DiSEqC switches
and LNB’s. A protocol each time more required in modern installations.
The TI-330 is microprocessor controlled, making it very reliable and
accurate.

TI-340 DiSEqC checker
The TI-340 permits to check at any
point of an installation the presence and
the state of DiSEqC signals. A set of
LEDS signals indicates the presence in
the coax-cable of the following signals:
-Hi/Lo - Mini DiSEqC tone
-H/V - 22 kHz
-Position - 60 Hz
-Switches- 13 and /or 18 V
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.)
AMC/1 Master aerial
The AMC/1 master aerial is a dipole with
interchangeable arms (in function to the
band), mounted on a hand-held mast,
which, connected to field strength meter,
permits the value of the electric field intensity
at a particular 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.
