Detecting Ingress in the Field
The operator looks at the ingress present at the field test point
using the spectrum display on any of the receivers, then
switches to reverse ingress/noise to see the ingress at the head-
end for comparison. This time-saving procedure helps in
locating sources of ingress. An adjustable dwell time ensures
that even intermittent ingress is detected. The preamp and
low-pass filter also assures that even low-level ingress is seen.
The preamp and low-pass filter on the SDA-5000 assures that
ingress can be measured on devices with bi-directional test-
points or testpoint values of 30 dB or more.

PathTrak Field View
When a system is equipped with the PathTrak Performance
Monitoring System, system technicians can benefit from the
ultimate ingress fighting tool—the PathTrak Field View
option for the SDA-5000. With Field View, the SDA-5000
receives a return path headend spectrum broadcast from the
PathTrak unit and compares it with a return path spectrum
at any field testpoint. The side-by-side spectrum compari-
son instantly reveals to the technician whether the ingress
source is originating at the current testpoint or at a different
location. The comparative spectrum technique slashes
noise/ingress troubleshooting time, since the technician can
immediately verify whether corrective action performed in
the field (local trace) results in improvement in the headend
spectrum (remote trace).

Powerful Graphic Displays and
Common User Interface Allow
Technicians to Learn Fast
The results of all measurements are presented
to the user in clear, highly informative,
summary displays. The graphics present the
information the way the technician wants to see the
results—no further interpretation required. For exam-
ple, testpoint compensation values are entered at the
start of testing. Displays then calculate actual levels
automatically, minimizing field errors.

With SDA series products, all levels of instruments are
familiar to the technician, regardless of which is learned
first, because the same user interface conventions are used
across all product families (several examples of the icons
are included in this literature). The learning curve for a
progressing technician is considerably shorter than with
alternative test equipment. This means urgent upgrade pro-
jects make the most efficient use of limited resources when
SDA series products are used.
