How do I review L-band signal quality in Quantum?
Quantum provides several indicators and displays that help in checking the status and health of L-band corrections. These displays might differ slightly between hardware, for example, it will display L-band information from one source when connected to an LD8, and two different sources when connected to an LD900. The number of indicators may also vary depending on the size of the display panel.
The first place to check within Quantum to view the status of the L-band corrections is within the Correction Link Status panel. It provides high level information regarding various aspects of the L-band corrections in use.
It has four colour-coded radio button indicators: Enabled, Locked, Sync and Signal Strength, which show the health of the L-band beam being used (Auto/single beam shown on the left of the panel), where green indicates a healthy status. If a single beam has been manually selected, it also shows the Azimuth and Elevation of the satellite.

More information on the Correction Link Status indicators can be seen in the table below:

Another useful panel for reviewing the quality is Correction Link Signal Strength. This is a fuel gauge type view which provides real-time L-band signal strength indication. The view is colour-coded to give a clear visual indication if the signal strength is acceptable, where the green zone indicates a healthy L-band signal strength.
The Correction Link Signal Strength – Time Series view also shows a graphical plot of the L-band signal strength over the previous 10 minutes. Ideally, this should show a constant L-band strength of over 40dB.
Other views are also available which could help in checking the quality of the L-band corrections, including Correction Age, Correction Latency, Service Correction Availability and Correction Link Satellites. More information in these can be found within What Correction Information Views Are Available within Quantum?
