HP 83485B 40 GHz Electrical/10 Gb/s Optical Plug-In Module

The HP 83485B is similar to the HP 83485A. The optical channel has a built-in filter to provide a calibrated reference receiver for characterization of transmitters used in STM-64/OC-192 10 Gbit/s systems. The filter can be switched out for increased channel speed (for example, during rise and fall time measurements). The unfiltered frequency response is not flat and can cause waveform distortion in very high-speed optical pulse measurements. (For highest bandwidth and waveform fidelity, the HP 83482A is recommended). The companion electrical channel has a greater than 40 GHz bandwidth.
