The N3970A Optical Power Meter is used for field or laboratory
testing of fiber optic systems at typically 850, 1300, 1310 and
1550 nm. It features superb measurement confidence, ease of
use and reduced cost of ownership, and is for use by installers,
technicians and engineers.
Superior measurement confidence is achieved with a unique
Total Uncertainty specification over the full temperature ,
measurement and connector range, and a NATA traceable
calibration certificate. The display hold and back light facilities
help acquire readings, and the flexible memory helps record
your results
Autotest mode enables automatic
λ
(wavelength) detection and
attenuation measurement (in combination with an Autotest
source). A single or dual
λ
source and meter in Autotest mode
automatically measure single or dual
λ
attenuation in one
direction.
High operational reliability & availability is achieved with 250
hour battery life, 3 year recommended re-calibration cycle,
negligible warm up and no range-changing delays. Dark current
offset is not required. An external power input is also provided.
The combination of features enables reduced equipment
inventory, simpler training, shorter procedures, lower skill
levels and direct labour savings in many situations, combining
to give lower cost of ownership.
The innovative optical connector port provides drop protection
during use, and is dust protected by a snap on cover. The
interchangeable optical connector system is very versatile, and
easily disassembled for cleaning.
The simple user interface guides the operator through functional
sequences, and a hidden keypad is used to access advanced
features such as log/linear display, and memory functions.
