Description of the Agilent 11982A Lightwave
Converter
The Agilent 11982A lightwave converter converts an optical signal to an elec-
trical signal. The Agilent 11982A combines a PIN photodetector for the opti-
cal-to-electrical conversion. The electrical signal is amplified with a low-noise
preamplifier. The Agilent 11982A provides a general purpose optical-to-elec-
trical converter for lightwave frequency-domain and time-domain measure-
ments and can be used with oscilloscopes, spectrum analyzers, and network
analyzers.
The Agilent 11982A covers the wavelengths from 1200 to 1600 nm with dc to
15 GHz (optical) modulating bandwidth. Its 300 volts/watt (nominal) conver-
sion gain and 0.05% input optical reflections, significantly improves sensitivity
for characterizing lightwave devices. Each converter comes with a calibration
chart of instrument-specific data for frequency response and responsivity to
enable correct and accurate measurements.
