Raw BER Query-only; displays the raw bit error rate; this rate is the error
rate of the signal as it is received from the satellite, before error
correction is applied.
—
BER Query-only; displays the bit error rate; this value represents the
number of errors detected in the signal after error correction is
applied. This rate should be a zero for correct performance.
—
Rx Level Query-only; displays the power level of the input signal. value in .dBm
Peak Jitter Query-only; displays the difference, or jitter, between the STC
and PCR clocks.
value in ns
Details>Input>Status>ASI: allows you to query the presence of the ASI signal, as well as other transport stream parameters
Signal Query-only; displays if the ASI signal is present or not
Note: Signal is only available when
Details>Input>Config>Select>Input is set to ASI.

Transport Query-only; displays the lock status of the transport stream Locked, Unlocked
Rate Query-only; displays the output rate for the QPSK demodulator value in bps
Peak Jitter Query-only; displays the difference, or jitter, between the STC
and PCR clocks.

Details>Service: consists of two submenus, Number and Auto Select, which enable you to query and select the services available in
the transport stream.
Once you have selected a service, the Video Decoder, Audio Decoder, and User Data menus display the PIDs available for the
selected service.
Number Selects a service from those available in the transport stream.
Once a service is selected, the TDR6 processes that service
until:
■ Another service is selected
or
■ The selected service is no longer available in the transport
stream
Displays a list of available services.
■ Each available service in the transport stream
consists of a program number, a service
name, and a service provider.
■ If the transport stream does not contain
service names and providers, only the
program numbers are displayed.
■ If the transport stream input is not connected,
or if it lacks PSI information, the LCD displays
the message:
No services available
.
Auto Select Determines which service, including audio and data services,
that the TDR6 will select when any of the following events occur:
■ The TDR6 power is turned off and then restored, or the unit is
reset
■ The TDR6 loses and then re-establishes lock on the transport
stream
Note
: Since the typical SCPC transmission consists of a single
service that includes of a single video/audio pair, the Auto Select
feature was added to simplify the configuration process for
typical SCPC users. When the Auto Select feature is enabled, or
set to On, the decoder automatically selects the service with the
lowest service number first, then selects the video component
with the lowest PID, and finally selects the audio components
with the lowest PIDS for audio A/B.
With Auto Select set to Off, the decoder can be configured to
process a particular service, and within that service, to process
selected video and audio services.
■ On – when Auto Select is set to On, the TDR6
automatically selects the first available service
in the transport stream.
Note
: If you change the Auto Select function to
On after you have selected a service, the
TDR6 will continue to process the service you
selected until one of the events occurs, then
the TDR6 selects the first available service in
the transport stream.
■ Off – when Auto Select function is set to Off,
the TDR6 searches the transport stream for
the last service you manually selected.
If the service is found in the transport stream,
the TDR6 selects the service, and the LCD
displays the program number, service name,
and service provider.
If the service is not found in the transport
stream, the LCD displays
Service Not
Available
, the TDR6 does not select a service,
and no video, audio, or user data will be
output.
