The Keysight N7751A combines an attenuator with 2 front-panel power meter channels, offering exceptional performance at a low price. The power meters permit measurements from any point in the measurements setup and assist in calibrating power offsets with respect to the attenuator output.

Extension of N77xx-series

The N7751A attenuator is an extension to Keysights high density N77xx-family that establishes a new standard in space-saving fiberoptic instrumentation.

Features and Benefits

Compact instrument combines and integrates multiple functions for setting attenuation and power levels and optical power measurement to reduce CAPEX and floor space.

Fast and precise setting of optical power levels with settling times of 100 ms for improved test throughput.

Active power control to keep output power constant

The power meters support convenient power offset calibration of the attenuators.

The instrument can be controlled via LAN and USB, as well as GPIB for compatibility with existing equipment.

An easy-to-use and intuitive graphical user interface software speeds up the integration process.
