The SAU125 250W Solid State UHF TV Amplifier is composed of a 3U drawer
which can be mounted on a 19” standard rack.
1.1
Mounting Procedure
-
Insert the drawer in its place on the rack and fix it with four rack screws.
-
Connect the 220V (110V), 50/60Hz supply to the power plug located on the rear panel (Fig.
7.1, ref. 1).
-
Connect the RF Input connector located on the rear panel ( Fig. 7.1 ref. 2) to the RF cable
coming from 5W RF Amplifier (exciter).

1.2 Set-up Procedure
In this paragraph are described the tests and alignments to be performed on the
SAU125. For this purpose, the following instruments are necessary:
-
Spectrum analyzer, 0.1 to 1000 MHz with tracking generator TEK 2712 or
equivalent.
-
30dB –300W attenuator, BIRD 300A FFN 30 or equivalent.
Should any malfunction be detected, refer to chapter 6 for the specific
troubleshooting procedures.
1.2.1 Initial Tests
Once the procedure described in paragraph 7.1 has been carried out, perform the
following operations:
a)
Perform set-up as shown in Fig. 3.2 and turn-on the SAU125 by moving
the ON/OFF switch of the front panel (Fig. 4.1 ref. 1) to ON position and
verify that the display goes ON (Fig. 4.1 ref. 6).
b)
Preset the spectrum analyzer to the frequency band in accordance to the
selected TV channel.
c)
Check that the SAU125 GAIN is
≥
13dB. (Small signal)
d)
Turn OFF the equipment, and remove the measurement set-up.
