Condition: Used

In good working condition.

From the manufacturer:

Measurement capability: attenuator

settling time: 20 ms attenuation, 100 ms power

0.1 to 1000 dB/s attenuation transition speed (selectable)

+23 dBm input power

≤ 1.2 dB insertion loss

Measurement capability: power meter

Wavelength range: 1260-1640 nm

Power range: -80 to +10 dBm

Polarization dependence: <0.01 dB

System capability

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

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

Includes powerful and user-friendly GUI software

Two instrument configurations can be stored and recalled

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 Keysight’s 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.

Applications

Optical transceiver testing

Optical network integration testing
