RF Carrier ID
State
On, Off, Last State. The Carrier State set what/when?
FEC Rate 1/4, 1/3, 2/5, 1/2, 3/5, 2/3, 3/4, 4/5, 5/6, 7/8, 8/9, 9/10, 13/45, 9/20, 8/15, 11/20, 5/9, 26/45, 28/45, 23/36, 25/36,
32/45, 13/18, 11/15, 7/9, 77/90. Indicates the ratio of the useful information to the useful information plus the
redundant information used for error correction. The availability of the options is subject to the value set for the
Modulation Standard parameter.
Symbol Rate 1.0 – 45 MSym/s (or 0.132 - 66 MSym/s if the VOY/SWO/HSYM license is available - extended range)
Maximum Input
Data Rate The maximum data rate of the transport stream the modulator can accept for the given modulation settings. Read-
only parameter.
Output Select L-Band, IF. The RF output used for sending the signal from the Voyager to the Up-converter. Depending on the
choice made here the availability of related menu items changes.
Frequency Input
Mode L-Band Frequency
1
, IF Frequency
2
, Uplink Frequency. The mode the frequency is treated. For L-Band Frequency
1
or IF Frequency
2
the RF center frequency of the respective output is directly entered. For Uplink Frequency, the RF
center frequency is calculated from the Uplink Frequency and the Up-converter Frequency.
L-Band
Frequency
1,3
950 – 2150 MHz. The center frequency of the signal output through the L-Band output.
IF Frequency
2,3
50 – 180 MHz. The center frequency of the signal output through the IF output.
Uplink
Frequency
4
The frequency the signal is converted to by the up-converter fed from the Voyager II.
Output state
On, Off. Read only parameter that reflects the output state set in the Line-up or in the Advanced/Satellite Modulator
Option Card/Output Parameters menu. The state is also reflected by icons, see Front Panel Screens.
Reduced L-Band
Line-up Power
1
-40 – 5 dBm. The L-Band output power set when the satellite modulator Output State is changed to On during boot-
up or when rebooted with the Output State allowed to stay on after reboot.
Reduced IF
Line-up Power
2
-30 – 5 dBm. The IF output power set when the satellite modulator Output State is changed to On during boot-up or
when rebooted with the Output State allowed to stay on after reboot.
Up-converter
Power
1
Off, 15V, 24V. Turns on or off a DC voltage to supply the up-converter fed by the Voyager II. The presence of DC
power is also confirmed by an LED on the modulator card.
Output Power-
up State On, Off, Last State. The Output State set after the unit is booted. By Last State the unit keeps the Output State set
before reboot.
Clock Reference
Mode Internal, [External]. External mode is not supported by the current hardware configuration.
1 Applies to L-Band output only.
2 Applies to IF output only.
3 Accessible if Frequency Input Mode is set to other than Uplink Frequency.
4 Accessible if Uplink Frequency is set for Frequency Input Mode.
4.4.1.4 Bit Rate Tracking Menu
The Bit Rate Tracking Menu displays the Transport Stream Bit Rate settings. The
menu options are shown in
Table 4.8.
