HP 83486A Optical Electrical Module

The HP Agilent 83486A optical/electrical plug-in module incorporates two measurement channels, one optical and one electrical. The electrical 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 calibrated, integrated optical channel has over 2.85 GHz bandwidth and allows easy, precise measurements of single-mode or multimode optical signals.

The integrated optical channel reduces electrical 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 to provide both accurate display of the received optical waveform in optical power units and measurement of the signal’s average power. In addition, the User Cal feature provides for consistent accuracy at any wavelength between 1000 nm and 1600 nm using a source and power meter.

The Agilent 83486A optical/electrical plug-in module also is a calibrated SONET/SDH reference receiver that is measured to conform to ITU-TS G.957 and TANWT-000253 frequency response requirements (Option 040) or to reference receiver specifications for Fibre Channel (FC) 1063 and Gigabit Ethernet for transmitter compliance testing (Option 041). By pressing a front-panel key or issuing an GPIB command, a filter is inserted or removed from the measurement channel by a very repeatable Agilent Technologies microwave switch. The switch removes the potential variability and the time wasted by manually inserting and removing the filter when alternating between highfidelity waveform characterization and SONET/SDH compliance testing.

The electrical measurement channel may be used to perform measurements on tributary electrical signals, to evaluate receiver performance in transceiver testing, for measurements with Agilent Technologies’wide range of external optical receivers, or for general purpose measurements.
