Narrow Band Guard Interval
This option applies to SOLO4 transmitters only. The Guard Interval
defaults to 1/16. Interval 1/8 is also available for very long range
(aircraft downlinks) applications.
Narrow Band Modulation
This option applies to SOLO4 transmitters only. The COFDM mode can
be changed between QPSK and 16QAM. QPSK is the default mode
and will give the strongest most rugged RF link performance. Selecting
16QAM reduces the link performance by 5dB but improves the link data
throughput, giving significantly better video quality.
Note: The terminology DVB-T refers to the 8,7,6MHz wide bandwidth modulation employed in the
SOLO2 products. The SOLO4 product is also capable of DVB-T, but this mode is not recommended
for normal operation
DVB-T Service Name
Applicable in DVB-T mode only, defaults to Unit 1. This should not be
changed in normal operation
DVB-T FEC
Applicable in DVB-T mode only, the default FEC is ½. Other FEC rates
will all reduce the range of the product, but will improve image quality
and capacity of the link.
DVB-T Guard Interval
Applicable in DVB-T mode only. The Guard Interval defaults to 1/32.
Other guard intervals such as 1/16 or 1/8 are available for very long
range (aircraft downlinks) applications.
DVB-T Modulation
Applicable in DVB-T mode only, the COFDM mode can be changed
between QPSK, 16QAM and 64QAM. QPSK is the default mode and
will give the strongest most rugged RF link performance. Selecting
16QAM reduces the link performance by 5dB but improves the link data
throughput, giving significantly better video quality.
