System functions

Provide one attenuator channel and two power meters in one half-width rack

Fully compatible with programs for the Keysight 8157x and 8156x modular attenuators

Includes powerful, easy-to-use graphical user interface software

Can store and recall two instrument configurations


The Keysight N7751A combines two front panel power meter channels to deliver outstanding performance at a low price. When considering the attenuator output, the power meter can measure at any point in the measurement setup and contribute to power offset calibration.

Extension of the N77xx series

The N7751A attenuator, an extension of the high-density Keysight N77xx family, sets a new standard in space-saving for fiber optic instruments.

Features and advantages

A compact instrument with integrated functions for attenuation settings and power level and optical power measurements to reduce capital expenditures and floor space.

Quick and precise setup for optical power levels and set setup time to 100 ms to increase test throughput.

Active power control keeps output power constant

The power meter supports the use of an attenuator for convenient power offset calibration.

The instrument can be controlled via LAN, USB and GPIB to be compatible with existing equipment.

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