Optical Attenuator & Power Meter

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.Features：Measurement capability: attenuatorsettling time: 20 ms attenuation, 100 ms power0.1 to 1000 dB/s attenuation transition speed (selectable)+23 dBm input power≤ 1.2 dB insertion lossMeasurement capability: power meterWavelength range: 1260-1640 nmPower range: -80 to +10 dBmPolarization dependence: <0.01 dB
