Input frequency/transponder selection
Use this menu to select the input frequency, either
by entering the frequency value in MHz or the
transponder number, depending on the selected
mode (MANUAL, XPNDR STACK or XPNDR LEGACY).
The display will show the following information in
each case:
- TUNER A -
SELECT INPUT
FREQUENCY
1500 MHz
- TUNER A -
SELECT INPUT
TRANSPONDER
1R= 974MHz
Press circle to enter the “Edit mode” and the last
line of the display will start to blink (cursor ON).
In manual mode (setting by frequency), you can
move the cursor to any of the 4 frequency digits by
pressing the
●
button.
In transponder mode, the transponder’s number
will blink displaying the corresponding L-Band
input frequency .
Input modulation selection
This menu only appears when the user has
selected the manual modulation mode in the
corresponding CONFIGURATION menu.
- TUNER A -
SELECT INPUT
MODULATION
TQPSK 7/8
In this case the user has to manually select the
input modulation, the available choices are:
QPSK Scan
8PSK 2/3
8PSK 3/4
8PSK 4/5
8PSK 5/6
8PSK 8/9
TQPSK 1/2
TQPSK 2/3
TQPSK 3/4
TQPSK 5/6
TQPSK 7/8
Input baud rate selection
This menu only appears when the user has
selected the manual modulation mode in the
corresponding CONFIGURATION menu. In this case
the user has to manually enter the baudrate of the
input signal (between 10,000 and 30,000 Kbaud).
- TUNER A -
SELECT INPUT
SYMBOL RATE
22.000 Kbaud
Output frequency/ channel selection
This menu allows the user to select the output
frequency/channel according to the mode selected
in the corresponding CONFIGURATION menu.
- TUNER A -
SELECT OUT
CHANNEL
2 = 57MHz
- TUNER A -
SELECT OUT
FREQUENCY
57MHz (2)
In channel mode, the CATV QAM channel is
selected (see Appendix 1). The last line of the
display will show both the output channel number
and its center frequency (Channel # = center
frequency).
In frequency mode, the user can select any
frequency value between 57 and 999 MHz and
the corresponding channel number is displayed
between brackets.
The two outputs in an HDTV TRANSMODULATOR
- Dual 8PSK to QAM are completely agile, so the
two QAM channels can be positioned anywhere
in the spectrum allowing for maximum flexibility .
