Atec Agilent-8591C User Manual
A complete test solution for your
cable TV system
The Agilent Technologies CaLan 8591C is the
industry’s only one-box tester for all RF and video
measurements. With this analyzer you can make
RF and video measurements without interrupting
your cable TV system. The CaLan 8591C is a f lexible troubleshooting tool and an automatic system
tester. Non-interfering measurements are performed
at the push of a button and can be made automatically.
The flexible hardware and software design lets you
easily upgrade the analyzer to accommodate changes
in required measurements and measurement techniques. For added flexibility, NTSC format is standard, with options available for worldwide PAL and
SECAM formats and frequency plans.
CaLan’s cable TV analyzer provides all this performance in a rugged, portable instrument ideal
for field use. It comes in a durable carrying case
that makes it easy to transport and that protects it
from moisture and dirt. And the analyzer is fully
operational within the case, so you never need to
remove it.
Agilent CaLan 8591C cable TV analyzer
All specifications apply over 0°C to +50°C. The
analyzer will meet its specifications after 2 hours
of storage at constant temperature within the operating temperature range, 30 minutes after the analyzer is turned on and after CAL FREQ, CAL AMPTD
have been run. Character-istics provide useful, but
non-warranted, information about nominal performance.
