2.6.2 Detector Unit

The Detector receives the transmitted pulsed radiation signals from the

Flash Source. The signals are then amplified and fed into an analog to digital

signal converter to be processed by the internal microprocessor. When the

signals drop below a prescribed level, the internal microprocessor will

compensate for them. This will allow the signal to be maintained even in

severe weather conditions. The data is sent to the output interface section.

The front window of the Detector is heated to improve performance in icing,

condensation and snow conditions.

There is one detector type that is suitable for all Quasar models 901, 902,

903 and 904 – P/N QR-X-11X.
