N775xA and N776xA series compact multi-channel attenuators and power meters are a new class of remote controlled fiberoptic instruments for optical transceiver and network integration test. High setting speed of attenuation and power as well as power measurement capability, combined with USB, LAN and GPIB interfaces provides increased throughput and operational efficiency to meet today's challenges in manufacturing. Operation Modes All attenuators feature both attenuation mode and power control mode. In attenuation mode, the calibrated value of attenuation in dB can be set. The attenuation can be changed at up to 1000 dB/s or the rate can be set to values in the range 0-1000 dB/s for single-mode and 0-80dB/s for multimode units. The power control functionality allows you to set the power level at the attenuator output. The instrument uses the feedback signal from a photodiode after a monitor tap, both integrated in the instrument, to set the desired power level at the output of the module (Figure 1 and Figure 2). When the power control mode is enabled, the module automatically corrects for power changes at the input so that the output power level you set is maintained. Absolute power levels can be set with high accuracy after an initial offset calibration for the uncertainties at connector interfaces. 03 | Keysight | N77-Series Attenuators - Data Sheet Power measurements value pairs can be stored in a table Key specifications to compensate for wavelength- In addition, the Keysight N7751A dependent effects in the optical and features and N7752A attenuators include two path of the set-up. This allows you extra optical power meter channels
