The N7751A combines a power-monitored attenuator with two extra power meter channels. It is a compact remote-controlled instrument with fast attenuation and power adjustment, combined with fast power measurement capability.
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.
Key Features |
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. |
