The Keysight N7745A optical power meter features eight channels of power probes, providing increased throughput and efficiency to meet today's manufacturing challenges. Designed for characterizing multi-port optical devices, these optical power meters provide industry-leading solutions for device connectivity, high-speed measurement data acquisition, and fast data transfer for post-processing. The multi-port power meters provide a fast measurement solution for all multi-port devices such as multiplexers, PON splitters, wavelength selective switches (WSS) and ROADMs, as well as compact test sets for testing multiple single-port devices simultaneously.
The N7745A power meter saves channel space, which is an industry first. This feature is further enhanced by the ability to integrate multiple devices into a single setup through parallel programming of LAN or USB connections.
The multi-port power meter was developed using LXI technology and is compliant with LXI Class C. LXI stands for LAN eXtension for Instrumentation and establishes an instrumentation standard for devices that use Ethernet (LAN) as their primary communication interface. As a result, it is an easy-to-connect instrument with an integrated web browser that provides convenient configuration of instrument functions.
The new power meter features the unprecedented N7740 fiber optic connectivity concept, a four-core cable adapter with a flexible snap-in quick-lock mechanism. The device under test can be easily connected to the four-core cable adapter even when the instrument is measuring other devices. The four-core cable adapter can then be quickly locked, providing a highly precise connection that can be connected and disconnected repeatedly. With the four-core cable adapter, you can align the connector keys more simply, especially for rack-mounted instruments, and more easily connect the ports in the desired order, avoiding connection errors or connector damage.
