Keysight N7711/4A Single and 4-Port Tunable Laser System Source

Initial Inspection

The Keysight N7711A and N7714A tunable lasers are single-port and
four-port sources, available with C-band or L-band wavelength
coverage. The narrow linewidth and offset grid fine-tuning capability
of the N7711A and N7714A make them ideal sources for realistic
loading of the latest transmission systems.
To owners of Agilent's proven Lightwave Measurement System the
81950A tunable laser source module offers the same features as the
N7711A. The 81950A plugs into the 8163B and 8164B mainframes. For
additional information about the 81950A please refer to the Compact
Tunable Laser data sheet, publication no. 5988-8518EN.
All models can reach any wavelength point within their specified
wavelength range just like all other Keysight tunable lasers. In this
mode, code compatibility with existing test setups based on Agilent's
range of full-size and compact tunable lasers is a great asset. In system
loading applications, it may be preferable to grid-tune the lasers like
system transmitters, simply by changing the channel index. The
channel grid is adjustable to standard ITU-T grid spacing like 50 GHz,
and to arbitrary grids. Likewise, the zero frequency (base channel) of
the chosen grid is adjustable. A 12 GHz fine-tuning range allows de-
tuning the frequency.
Targeted for high test throughput, lowest cost-per-channel, and narrow
footprint, all members of Agilent's 77-Series optical test instruments are
built on a common platform and a common PC-based user interface. A
complete set of control interfaces including LAN, USB2.0 and GPIB
simplifies integration with manufacturing control systems. Code
compatible to Agilent's Lightwave Measurement System modules, the
new instrument generation can serve as plug-in replacements in
existing test solutions. The N77 viewer software allows to control all
features of the N7711/4A tunable laser sources.
Inspect the shipping container for damage. If there is damage to the
container or cushioning, keep them until you have checked the contents
of the shipment for completeness and verified the instrument both
mechanically and electrically. The Function Tests give a procedure for
checking the operation of the instrument. If the contents are incomplete,
mechanical damage or defect is apparent, or if an instrument does not
pass the operator's checks, notify the nearest Keysight Technologies
Sales/Service Office.
