Other main functionalities are:
• continuous transmitter’s operations (100% duty cycle).
• Output power selectable between two values (Phi and Plo), each of
which can be SW set to a nominal value between 10 and 110 Watts.
• final stage protected against excessive mismatching output power. In
the case that VSWR remains above a set threshold (eg ReturnLoss =
5dB) for more than a fixed time, the module is able to send an alert
and the output power will not exceed a safety value (eg ≤ 10watt).
• temperature threshold alarm: if the temperature remains above a set
value for more than a fixed time, the module is able to send an alert
and will ensure that the RF output power will not exceed a predetermined safe value.
The front panel is provided with bi-color leds to help in troubleshooting the system. The table below
describes the meaning of the leds:
