3.1.2.3

Sensitivity versus compression modes

As the end-to-end gain is adjusted by the user, various attenuators in the Sentinel 3 system are adjusted
to maintain the programmed gain.

When the system is set to favour sensitivity, these automatic adjustments are preferentially made in the
transmit head to maximise the system’s sensitivity, but this comes at the expense of system’s
compression point.

To configure this mode the signal magnitude setting should be set to “small”.

If the system is set to favour compression, these automatic adjustments are preferentially made in the
receiver module to maximise the system’s compression point, but this comes at the expense of the
system’s sensitivity. This adjustment can be made on the settings screen as shown below. To configure
this mode th

e signal magnitude setting should be set to “large”.

3.1.2.4

Thermal compensation

The Sentinel 3 system supports a thermal compensation feature that works to maintain the set gain value
over the operating temperature of the product. Once the overall link gain is set on the Graphical User
Interface (GUI) by the user, the system monitors any ambient temperature fluctuations and transparently
adjusts the internal attenuators to keep the actual gain within 0.25dB of the set value.

If a user is concerned about continuous gain adjustments occurring during their measurement cycle, this
feature can be de-activated using the GUI. In this case the last attenuator set value is retained with no
further adjustments being made until the user re-activates the feature.

An intermediate mode can be selected that restricts the thermal check and adjustment routine, only
allowing it to occur when the user manually changes the set gain value on the GUI or by remote
command. This mode achieves a reasonable degree of gain accuracy whilst preventing gain adjustments
being made mid-measurement.

3.1.2.5

Received Light Level (RLL) Automatic Gain Control (AGC)

The system can be configured in a number of different ways. Different fibre optic cable lengths can be
connected between the remote transmitter and local receiver modules and a number of breakout
solutions can be placed between them. To accurately realise and maintain the user set gain value for all
