HP 83487A Optical Electrical Module

The Agilent HP 83487A 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 750 nm and 860 nm using a source and powermeter.

The Agilent 83487A also is a calibrated reference receiver that is measured to conform to specifications for Fibre Channel (FC) 1063 and Gigabit Ethernet for transmitter compliance testing. 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, and maximizes measurement repeatability.

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.
