The Agilent 83486A Optical/Electrical Plug-In
Module
The Agilent 83486A optical/electrical plug-in module incorporates two mea-
surement 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 chan-
nel 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 aver-
age 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 ref-
erence receiver specifications for Fibre Channel (FC) 1063 and Gigabit Ether-
net 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 mea-
surement 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 high-
fidelity 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.
