Figure 25: NewStream SNG Information Touchscreen - Frequency Tune
SNG Information - Frequency Tune Mode - IDU Touchscreen Control
To change settings within the SNG Information touchscreen, in Local Mode, press
the Mode: botton to toggle to Frequency Tune Mode [see Figure 25]. Next, press the
Power: button to display the numeric keypad, type the value in dBm and then press
the Enter key on the keypad to set the L-Band power level. L-Band power settings
range from -40 to 5 dBm. When you press the CW [Carrier] button [Figure 5 item D], the
power level selected is displayed in the lower right of the touchscreen below the red bar
graph, in the lower right of the touchscreen. The CW toggle will disable the Mode and
Frequency settings while the Carrier is On.
When you press the Frequency: button, the numeric keypad displays allowing you to
set the SNG frequency. You must set the Block Up-converter frequency to the correct
level, which is dependent on your system’s Block Up-converter. Press the Enter key
shown on the keypad after each of the keypad actions.
If you want to use the IDU front panel buttons and rocker switches to set Satellite
frequencies, select an SNG Preset and start with the rocker switch [Figure 5 item G],
that controls each digit of frequency, as displayed within the Frequency 16x2 display.
You can move the cursor within the Frequency 16x2 display to increment the digits of
the numeric display using the left/right arrow buttons [Figure 5 items K and L]. Selecting
the frequency setting feature automatically sets the cursor to the leftmost position and
causes the Enter button [Figure 5 item I] to start blinking amber. Pressing [Figure 5 item
L] right arrow allows movement of the cursor to the right by one digit and then using the
rocker switch [Figure 5 item G] you can increment that digit up or down. You can set
the cursor to the left by using the left arrow [Figure 5 item K]. When you are satisfi ed
with the entry, press the Enter button [Figure 5 item I] to save the new frequency. If no
action occurs after 15 seconds, the frequency window reverts to the last frequency set.
Frequency settings persist from one power cycle to the next.
