View Screen
The View screen allows the following to be viewed:
•
Graphs. These include spectrum, constellation, IP throughput and time-based
performance graphs. None of these interfere with the service being provided by the
modem. Note that when viewing demodulator graphs, such as the constellation or
spectrum, it is necessary to select the specific demodulator to be viewed. Graphs
of Tx QoS stream throughput over time are also available and include the stream
data rate (in packets per second and bits per second), the number of dropped
packets and a count of the errored packets.
•
Alarms. System alarms and warnings can be viewed.
•
Log. The system log can be viewed and optionally emptied. The log contains
information on all alarms and other notable events. The log contains space for
thousands of entries. The oldest entries are deleted when space is required for new
entries.
•
Setup. This provides a succinct summary of the operational setup of the modem.
•
Unit. This provides manufacturing information (including the software version
number and the hardware fitted), power supply voltage levels, modem temperature
indication, loopback status and the IP address of the M&C port (for when this has
been set using DHCP).
•
SAF. This displays all of the SAF features for the modem, indicating whether they
are enabled or disabled. It also shows how many test shots remain along with the
remaining test time. Information on temporary SAF (such as any temporary
licenses) is also available.
•
Tx QoS. This presents metrics for the shared outbound carrier in terms of total
throughput and per-stream throughput, including dropped packet counts and
current stream data rates (in packets per second and bits per second).
6.2.27.1 View->Graphs->Spectrum; Rx Spectrum Monitor
The Rx Spectrum Monitor shown in Figure 6-58 is a powerful real-time spectrum analyser
within the modem that is used to view the received signal spectrum.
