N7764A Keysight 4-channel Variable Optical Attenuator

Measurement function: Attenuator

• Build-up time: 20 ms attenuation, 100 ms power

• 0.1 to 1000 dB/s Attenuation conversion speed (optional)

• +23 dBm Input power

• ≤ 1.2 dB insertion loss

Measurement function: Power meter

• Wavelength range: 1260 - 1640 nm

• Power range: -80 ~ +10 dBm

• Polarization dependence:<0.01 dB

System function

• Provides one attenuator channel and two power meters in a half-width rack

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

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

• Can store and recall two instrument configurations

The Keysight N7751A integrates two front-panel power meter channels to deliver outstanding performance at a low price. The power meter can measure at any point of the measurement setup when considering the attenuator output, and helps with power bias calibration.

Expansion of the N77xx Series

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