a. Input menu
The fi rst main menu allows you to select for the
input signal: the
frequency or channel , the off set
( channel mode only), the bandwidth and the
preamplifi ers powering .

Bw: 8MHz
Preamp: 00V
To make a change press the key until the desired
parameter fl ashes. Then, this fi eld can be changed
by means of the keys and .
You can select any output frequency value between
177,5 - 226,5 MHz (VHF) and 474-858 MHz (UHF).
The decimal part depends on the frequency step
selected (
see extended menu b ). If the frequency
step is defi ned as 125KHz, decimal part values
allowed are: 0, 125, 250, 375, 500, 625, 750 and 875
KHz. If it is a 166 KHz step, then the values allowed
are: 0, 166, 333, 500, 666 and 833 KHz.
Possible COFDM Bandwidths are: 7MHz or 8MHz.
Available voltages to power preamplifi ers are: 0, 12
and 24 Vdc

In frequency mode you can select any output
frequency value between 177.5 - 226.5 and 474 -
858 MHz. The decimal part depends on the step
of frequency chosen (
see extended menu b ). If you
select a steps of 125 KHz the permitted values for
the decimal part are: 0, 125, 250, 375, 500, 625, 750
and 875 KHz. With a steps of 166 KHz the possible
values are: 0, 166, 333, 500, 666 and 833 KHz.
In channel mode you can choose an output
