The Keysight N7751A is a 1-channel optical attenuator and power meter designed for high-performance optical communication systems. This compact, half-width rack unit instrument integrates multiple functions for setting attenuation and power levels, alongside optical power measurement capabilities, to reduce capital expenditure and optimize rack space. It is an extension of Keysight’s high-density N77xx-family of fiber optic instrumentation.
