When the Summed Alarm indicator is
red, if the cursor is placed over the
indicator, a message tab will appear
briefly describing the reason for the
alarm condition.
Seven additional parameters are displayed with
numerical values. The first group of parameters
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 con-
verter local oscillators are synchronized to their
respective RF signals. The second group of param-
eters using a status indicator 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 nor-
mal range. Also, the Form-C contacts inside the
cabinet will change states. ADC or DAC Overflow
indicator shows that the input power to the branch
is too high.
If a fault occurs, press the clear errors
button on the left side of the page. If
the error reappears right away then
trouble shooting will need to take
place.
The first four numerical parameters are real-time
indications of the module and power amplifier tem-
perature/current values. AGC Attenuation updates
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.
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 14.
