When one set of tuning parameters has been defined it is possible to click the button
Import from NIT
in
order to have the other frequencies automatically added to the list, as defined in the Network Information
Table(s) analyzed by the probe. Default values will be assigned to parameters that are not part of the NIT.
The following parameters are defined for each tuning entry:
DVB-T/T2 — Tuning setup — Edit:
Name: A name should be assigned to each tuning configuration.
Frequency:
The channel center frequency in MHz. Note that the center frequency of
DVB-T/T2 transmissions is sometimes changed by an offset of
±
167 kHz
in order to avoid interference with neighboring analogue channels. In this
case this frequency setting should be adjusted accordingly.
Channel spacing: The channel spacing in MHz
Transmission system:
Selection of DVB-T or DVB-T2 transmission system. The Test calibrate
mode is used during manufacturing.
DVB-T2 profile: Determines current profile of DVB-T2 signal:
Base
Lite (supported form DVB-T2 v1.3.1)
PLP selection:
The Physical Layer Pipe to be demodulated and analyzed. A specific PLP-
ID may be selected or PLP selection can be set to ‘Auto’. Only applicable
for DVB-T2.
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
Reference table set:
The Reference table set selection is used to compare the tables in the
transport stream with a set of stored tables. These tables are defined in the
ETR 290 — Gold TS thresholds view.
DVB-T/T2 thresholds:
Selection of the DVB-T/T2 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
Extract thumbnails:
When enabled, the probe will generate thumbnails for this tuning whenever
tuned to it. If not, they can be generated manually by opening the thumbnail
pop-up from the
Main — Thumb overview
and
ETR 290 — Services
views.
Enable tuning:
If this box is checked, the transport stream associated with the current
frequency will be monitored
It is also possible to add new frequencies manually by copying existing tuning list entries using the
Duplicate highlighted button.
