Note: The preamp gates are not protection pulses. The preamps are self protecting
using diodes, and the gate is required in order to ensure that low power pulses can pass
the protection diodes.
7.4.1.2 Board Temperature Control
The temperature sensitive parts (Master Oscillator, Receiver Gain Stages, Filters, etc)
are all within a temperature controlled zone on the main board, which is thermally iso-
lated with a blue foam cover.
The temperature is controlled by a digital PID algorithm which runs in the background on
