HP/Agilent 86105A - 20GHz Optical / 20GHz Electrical Module
The Agilent 86105A incorporates two measurement channels—one optical, the second electrical. Each channel has two selectable bandwidth settings. In the lower bandwidth mode of 12.4 GHz, oscilloscope noise performance is excellent, while the 20 GHz mode allows greater fidelity for high-speed signals. The optical channel also has a switchable filter to produce a calibrated SDH/SONET reference receiver. 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 1310 nm and 1550 nm to provide accurate display of the received optical waveform in optical power units and measurement of the average power of the signal. Switchable filters for compliance testing at 155, 622, 2488 or 9953 Mb/s are available.
