CHAPTER 8: FILES
8.1
INTRODUCTION
StealthTrak and SAM 4040D have non-volatile memory that can is
used to store data from field measurements for viewing at a later
time. You can retain these files in the unit for later review. Or, with
Wavetek’s StealthWare PC software, you can upload them to a PC.
Files loaded onto a PC can be viewed with the computer, printed,
and archived. Or, these files can be downloaded into another
StealthTrak/SAM 4040D for viewing in the field. The latter use is of
benefit with comparing past and current measurements of a given
CATV system test point.
In addition to viewing files, they can be printed, either directly from
the instrument, or via a PC using StealthWare. These printouts are
useful for proof-of-performance reports, troubleshooting and
analysis, and for other documentation purposes.
The following types of measurements can be stored as files:
•
Autotest
s.
•
Scan
s.
•
Sweep
s –including forward sweep, reverse sweep, reverse
amplifier alignment, and all sweep references.
•
Spectrum scans- including regular, zero-span, and CSO/CTB
measurements. Regular measurements can also include peak-
hold values.
•
Tilt
measurements
Channel plans and spectrum mode settings can be stored as files,
too.
All the files stored in your unit exist in a common pool of non-volatile
memory. When a file is stored, the instrument uses only the memory
actually required for the data. Different file types, or different settings
within the same type, can use different amounts of memory. To see
a display of how much memory is still available, press Function,
Chan keypad buttons. The bar graph next to the
File
soft icon
shows what percentage of memory is currently used.
