Keysight N7752A Optical Attenuator & Power Meter

Overview

The Keysight N7752A is a 2-channel optical attenuator combined with two power meter channels in a compact, half-width rack unit. This instrument provides fast attenuation control and power measurement capability, allowing users to measure optical power at any point in a test setup and to verify power levels precisely. The N7752A is fully compatible with existing software developed for Keysight's 8157x and 8156x modular attenuator systems.
