To carry out the configuration of each
QPSK-PAL module, it is necessary to use
the programmer and follow the following
steps:
5.1.- Normal menu
Insert the programmer in the front connector
of the QPSK-PAL programming module
(“PRGM”). First, the version of the software
in use, will appear. For example 4.00:
a.- Output channel
Once a couple of seconds have passed, the
first menu appears; the
output frequency ,
for example 174.25 MHz:
To change the value indicated, it is
necessary to press the
button, this will
make the selected digit blink on and off. By
using the
and buttons, the value of the
digit is changed. By pressing the button
again, the following digit is selected, that
can be changed in the same way. When the
cursor is on top of the decimal digit/s, and
5. - PROGRAMMING PROCEDURE
when pressing the and buttons, only
the following permitted digits will appear:
• .0 => .00 MHz
• .2 => .25 MHz
• .5 => .50 MHz
• .7 => .75 MHz
Input values range is from 46 to 862 MHz.
The selection of the output channel is
possible if the
channel mode has been
chosen (see extended menus). In this case,
the number of the chosen channel will
appear, for example, channel 5:
In this case, only the and buttons can
select the desired channel.
b.- Output level
By pressing the button, it is possible to
gain access to the output level selection. In
this case, there is no cursor for the selection
of the digit, and instead the
and
buttons are used to choose the output level
between 00 (minimum) and 99 (maximum).
For example, 85:
c.- Input Frequency
The following menu allows the user to enter
the
Input frequency . This is done in the
same way as the output frequency menu.
The
button allows you to select the digit
that you wish to modify, and you can either
increase or decrease its value using the
and
buttons. The range allowed for the
input frequency values is from 950 - 2150
MHz. For example, 1334 MHz:
d.- Symbol rate
By pressing the button, the following
menu appears on the display. This is the
Symbol Rate , for example 27.50 Mbaud:
This is done in the same way as the input
channel; the
button allows you to choose
between the different individual digits for the
symbol rate and the
and buttons
modify the selected digit. The range of
values permitted for the symbol rate is from
3.00 to 45.00 Mbaud.
If the cursor is placed on the digit that
