6.16.2 SAT Tuning setup
The following parameters are defined for each SAT frequency:
SAT - Tuning setup:
Name:
A name should be assigned to each frequency channel
Transponder
frequency:
The transponder frequency set to 1094 MHz when used with
the VB273 redundancy module.
LNB frequency:
The LNB frequency in GHz Set to zero when used together
with the 273 redundancy module.
LNB voltage:
The LNB voltage - may be 0V, 13V or 18V. Set to 0V when
used with VB273.
22kHz tone:
Enable or disable 22kHz tone. Set to DISABLED when used
with VB273.
DiSEqC:
The satellite front-end module supports Diseqc 1.2 signalling.
The
operator can enable a particular Diseqc message to be
transmitted
towards the antenna for each frequency defined in the tuning
setup typically used to control L-band switches. Specifically,
the message
sent has the format ( 0xE0 0x10 0x39 N ), where N is a byte
configurable by the user to be between 0x00 and 0x0f. This is
the command 0x39 "Write to Port group 1 (Uncommitted
switches)". Set to OFF when used with VB273.
Symbol rate:
The SAT symbol rate in Msymb/s. Set to the corresponding
symbol rate used by the modulators. Alternatively set to a
sufficiently high value to cover the highest symbol rate the
system will use. The demodulator will sync in on the symbol
rate actually used.
ETR thresholds:
Selection of the ETR threshold template that should be
assigned to the current frequency
PID thresholds:
Selection of the PID threshold template that should be
assigned to the current frequency
Service
thresholds:
Selection of the Service threshold template that should be
assigned to the current frequency
SAT thresholds:
Selection of the SAT threshold template that should be
assigned to the current frequency
VBC thresholds:
Selection of the VBC threshold template that should be
assigned to the current frequency
Disable tuning:
Disable tuning for frequencies that should not be monitored. If
tuning for a stream is not disabled it will automatically be part
of the round-robin analysis loop.
