Revision A
Operation Addendum, HPA Control Utility
Normal – the amplifier resumes operation in the last mode it was
operating. If the amplifier was on the air and there was a power
interruption, it will resume transmitting automatically. If the ampli-
fier was off the air for an extended period of time it will complete
filament time delay before going back on the air.
Off – The amplifier will resume operation by going into Standby
mode. If the power interruption was for an extended period of
time, the amplifier will complete filament time delay before going
into Standby.
On – the amplifier will resume operation by going into Transmit
mode. If the power transmission was for an extended period of
time, the amplifier will complete filament time delay before going
back on the air.
The amplifier does not manipulate the Waveguide switch based
upon these settings; it merely controls the power up state of the
amplifier.
Figure 8, Amplifier Startup Configuration
7.
Refer to Figure 9 on page 11. The “Configuration -> Max RF
Power Level” sets the maximum power that may be produced by
the amplifier. Once this output level is achieved, the amplifier will
increase attenuation in the event that input drive is increased.
This will continue until the input attenuator is at the maximum
attenuation, after which the amplifier will fault with an overdrive
condition.
