The Keysight N7744A and Keysight N7745A are LXI compliant optical
power meters with 4 or 8 power-sensor ports respectively. They address
productivity challenges by increasing throughput and operational
efficiency using industry-leading device connectivity, high-speed
acquisition of measurement data and fast data transfer for post-
processing.
The Keysight N7744A and Keysight N7745A are designed to
characterize optical multiport components, such as multiplexers, PON
splitters, wavelength selective switches (WSS) and ROADMs, in all
product phases from R&D to manufacturing.
The one rack unit (1U half-rack high) instrument can be operated alone
or with other units, by PC connected over LAN, USB, or GPIB.
The unprecedented N7740A fiber connectivity concept consists of a
quadruple adapter (quad-adapter) with a quick-locking mechanism. Up
to four fiber connectors from the device under test (DUT) can be
connected in a comfortable working position to one quad-adapter. The
push-on locking mechanism makes it easy and secure to attach the quad-
adapter to and remove the quad-adapter from the instrument in
seconds. With multiple quad-adapters, the measurement task can be
fully separated from the DUT connection task. This means a further
increase in test throughput. Where this is not an issue, traditional single
connector connectivity is supported as well.
These power meters are highly compatible with setups and programs
developed using the Keysight 816x modular power meters. They are
also easy to synchronize with Keysight tunable laser sources, to make
spectral measurements. The functionality for time-dependent
measurement has been extended with sampling at up to 1 MHz and
data logging of up to 1 million samples for each port.
The two-port N7747A and 4-port N7748A optical power meters bring
the highest performance in terms of sensitivity, noise and relative
accuracy to the compact N77 instrument platform. These instruments
combine the optical performance of the 81634B sensor modules with
the large memory, fast data transfer and small footprint of the N77
series platform. Eight high-sensitivity optical power meters now fit in
a single rack unit. Optical connections are made with the
interchangeable 81000xI connector interface system.
