Atec Acterna-JDSU-SDA-5000 - Manual (Page 7)

Automated tests can be scheduled to
perform either 24-hour FCC compliance
tests, or initiated immediately to log
performance at individual nodes,
amplifiers, or other testpoints. A wide
range of tests can be performed auto-
matically, including signal levels,
C/N, hum, and depth of modulation.
The operator designates which tests to
perform on which channels. Because
these tests are non-intrusive, it is easy
to test all parameters on all channels
at any time.
After a test is performed, the results
can be displayed on the SDA screen.
A PASS/FAIL indication on a variety
of limits can be set for FCC/CENELEC
or other government standards,
or system preferences. Data taken
during any automated test, or
sequence of automated tests, can be
viewed immediately with a PASS/FAIL
indication for each of the limits.
Specific stored measurement results
may be viewed on demand.
Data analysis with StealthWare
Test results can be printed directly to a
serial printer or uploaded to a PC using
Acterna StealthWare, a Microsoft ®
Windows ® -based data management
package, to store and include in cus-
tom reports. Stored sweep, scan, or
spectrum screens can be viewed on
the PC and analyzed with marker move-
ment and readout information in just
the same way as on the actual instru-
ment. A sweep graph overlay function
allows comparison of multiple RF
response variations over time. Old
sweep graphs may be downloaded
back into the SDA instrument for real-
time comparison.
Powerful and intuitive standardized
graphical displays
All measurement results 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,
with no further interpretation required.
For example, testpoint compensation
values are entered at the start of
testing. Displays then calculate actual
levels automatically, minimizing
field errors.
Reduced training time
With SDA Series products, all levels of
instruments are familiar to the tech-
nician, regardless of which is learned
first, because the same user interface
conventions are used across all prod-
uct families. The time needed for a
trainee technician to learn to use the
instrument is considerably shorter
than with alternative test equipment.
This means urgent upgrade projects
make the most efficient use of limited
resources when SDA Series products
are used.
