中古 HP 83485A Optical Electrical Module 場所 ガティノー, ケベック州, カナダ

The 83485A is an optical/electrical module. It incorporates two measurement channels, one optical and one electrical. Each channel has two selectable bandwidth setting. In the Lower bandwidth modes of 12.4 GHz, Oscilloscope noise performance is excellent, while the 20 GHz allows greater fidelity for high speed signals.
The integrated optical channel reduces mismatch loss variation by eliminating signal distorting cables and connectors associated with the use of external receivers in order to accurately characterize optical waveforms. The optical channel is calibrated at 1310nm and 1550 nm to provide both accurate display of the received optical waveform in optical power units and measurements of the signal average power. In addition, the user cal feature provides for consistent accuracy at any wavelength between 1200 nm and 1600 nm using a source and power meter.
