Seven additional parameters are displayed with
numerical values. The first group of parameters
using a status indicator include; Enabled which
indicates whether the branch is on or off, Ext Ref
which indicates whether the system is running on
an external or internal 10 MHz clock signal, and
Down and Up LO Lock which indicate if the down
converter and up converter local oscillators are
synchronized to their respective RF signals. The
second group of parameters using a status indica-
tor will be black under normal conditions and will
turn red to indicate a fault. The Alarm indicator is a
summed alarm and will activate when either the
module or power amplifier temperature/current
exceeds their normal range. Also, the Form-C con-
tacts inside the cabinet will change states. ADC or
DAC Overflow indicator shows that the input power
to the branch is too high.

in real-time and provides an indication of what the
AGC is doing. Input Power is a summation of all the
input signals to the branch. Output power also
updates in real-time and indicates the composite
power output for the branch. If a fault occurs, press
the Clear Errors button on the left side of the
screen. If the error reappears right away then trou-
bleshooting will need to take place.

FFT TAB
A Fast Fourier Transform feature is built into the
system software. This feature allows the user the
ability to display the output spectrum of the booster
in an amplitude versus frequency display. Pressing
the FFT tab will display the FFT screen as shown
in Figure 16. The FFT screen allows the user to
look at one link at a time. All of the signals input or
output from that link of the channel module can be
displayed. Also, any filters that are enabled can be
shown (see white waveform in example).

SYSTEM TAB
The system tab lists the control board software ver-
sions. A customer-designated location name can
be recorded and is useful in situations where multi-
ple boosters are used in the overall system design.
There is also a system logbook available on the
bottom of this page for use by field engineers when
working on the system. Refer to Figure 17.
