The N7751A combines a power-monitored attenuator with two extra front-panel power meter channels, offering exceptional performance at a low price. It is a compact remote-controlled instrument with fast attenuation and power adjustment, combined with fast power measurement capability. The power meters permit measurements from any point in the measurements setup and assist in calibrating power offsets with respect to the attenuator output.

• 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
  
• One or two attenuator channels and two power meters in one half-width rack unit
  
• Fully compatible with programs developed using the Agilent 8157x and 8156x modular attenuators
  
• Includes powerful and user-friendly GUI software
  
• Two instrument configurations can be stored and recalled
