• Detecting the warning thresholds set by the user (e.g. power delivered below
a specific threshold), which are made available to the user via the telemetry
connector
• Communicating with external devices
The amplifier’s control software is based on a menu system through which the
user may navigate using the following four buttons: ESC , , , ed ENTER . A
fifth button is provided for resetting any triggered alarms.
The PS module of this amplifier houses three rectifier/power supply switching units
that normally work in parallel mode and that provide a fair degree of redundancy to
the machine. Even if one of the power supply modules breaks down the amplifier
will keep working at reduced power.
A schematic view of the operating theory of amplifier is shown in the figure:
