Firstly, thank you for choosing an product.
products are solid state or thermionic tube transmitters that develop power
from a minimum of 2W to a maximum of 30KW.
Great care has been taken during the design of the protection circuitry to ensure compa-
tability with products from other manufacturers. However the best performance is achie-
ved when the equipment is used with other products manufactured by .
The unit has been designed to guarantee consistent performance over time, without the
need for special maintenance. The need for this is minimised by regular functional checks
of those components which are ventilated.
Operation of the unit is very easy and intuitive. Even so it is recommended that this manual
and other relevant documentation is read carefully before any operation is attempted.
Dear User,

3.4. Performance
>> Check
This performance check procedure is to be carried out if there is any doubt over
the integrity of the unit, due to any possible damamge occurred during transport. It should
be performed by expert personnel, capable of operating radiofrequency measurement
equipment.
The unit is calibrated using an FMAB (R&S) modulation analyser, therefore the
performance check equipment must be highly precised.
Signal reception
Audio Signal
Connect a RF generator to a “RX Signal” connector. Set a frequency with an output level
of - 50 dBm and a frequency deviation of +/- 75 KHz, in the unit range. Switch on the
unit, set the same frequency as that of the generator. Check the correct signal strenght in
the Measures Menu>> “RX Signal” (maximum acceptable error: +/- 2 dB).
Set a level of - 70 dBm on the generator and test the unit again following the instructions
described above.
Connect the Audio Analyser to one of the MPX outputs and verify the presence of the
demodulated signal (1KHz). Verify that the output level corresponds to the one set in the
“Setup Menu”>>”Output Level” (the input impedance of the Audio Analyser must either
exceed or equal 10 KOhm) and that the distortion is lower than 0.2%.
Set a level of - 70 dBm on the RF generator and repeate the testing following the instruc-
tions described above (the set squelch level must be either lower than - 70 dBm or exclu-
ded.)
