The Agilent 83487A Optical/Electrical Plug-In
Module
The Agilent 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 sig-
nals.
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 aver-
age power. In addition, the User Cal feature provides for consistent accuracy
at any wavelength between 750 nm and 860 nm using a source and power
meter.
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.
