2 Getting Started
N774xC Series of Multiport Power Meters
Keysight Technologies new N7744C and N7745C optical power meters
with four or eight power-sensor channels provide manufacturing users
with further increased throughput and operational efficiency to meet
today’s challenges in multiple-device and multiport testing. A family-wide,
common trigger concept, and a modern, browser accessible user
interface, make it convenient to configure the instrument’s functionality.
Successor to Keysight's popular N7744A optical power meters, the
N7744C has been further optimized for high measurement throughput
when characterizing optical multiport components, for example
multiplexers, PON splitters, wavelength selective switches (WSS) and
ROADMs, as well as for simultaneous testing of multiple single-port
devices.
These power meters achieve a level of space-saving channel density that
simplifies fiber handling for many-port device testing. This is
complemented by the ease of integrating multiple instruments into a
single setup with parallel programming over the LAN or USB connections.
A single N7744C/ N7745C is only one rack unit high and a half rack unit
wide.
With this new power meter comes the trusted N7740 fiber connectivity
concept, which is a quadruple adapter with a snap-on quick-locking
mechanism. The device to be tested can be connected to the
quad-adapters in a comfortable ergonomic working position, even while
the instrument is measuring another device.
The quad-adapters can be quickly snapped on to the instrument, to
provide reliable and repeatable high-precision connections. Use of the
quad-adapters simplifies aligning connector keys, especially for
rack-mounted instruments and makes it easier to connect ports in the
desired order, helping to avoid errors and connector damage.
A bare fiber version of the quad-adapter, N7740BI, can host up to four
bare fiber holders. Two types of bare fiber holder kits with four holders
each are available for fiber diameters up to 400 μ m (81004BM) and
between 400 μ m and 900 μ m (81009BM). The one-click zeroing adapter
N7740ZI allows quick and reliable 4-port zeroing of the power meters.
