Overview of Infiniium DCA-J
Features
Four instruments in one
The 86100C Infiniium DCA-J can be viewed as four high-powered
instruments in one:
• A general-purpose wide-bandwidth sampling oscilloscope.
PatternLock triggering significantly enhances the usability
as a general purpose scope.
• A digital communications analyzer
• A time domain reflectometer
• A precision jitter and amplitude interference analyzer
Just select the desired instrument mode and start making
measurements.
Configurable to meet your needs
The 86100C supports a wide range of modules for testing both
optical and electrical signals. Select modules to get the specific
bandwidth, filtering, and sensitivity you need.
Digital communications analysis
Accurate eye-diagram analysis is essential for characterizing
the quality of transmitters used from 100 Mb/s to 40Gb/s. The
86100C is designed specifically for the complex task of analyz-
ing digital communications waveforms. Compliance mask and
parametric testing no longer require a complicated sequence of
setups and configurations. If you can press a button, you can per-
form a complete compliance test. The important measurements
you need are right at your fingertips, including:
• Industry standard mask testing with built-in margin analysis
• Extinction ratio measurements with accuracy and repeatability
• Eye measurements: crossing %, eye height and width, ‘1’ and
‘0’ levels, jitter, rise or fall times and more
The key to accurate measurements of lightwave communications
waveforms is the optical receiver. The 86100C has a broad range
of precision receivers integrated within the instrument.
• Built-in photodiodes, with flat frequency responses, yield the
highest waveform fidelity. This provides high accuracy for
extinction ratio measurements.
• Standards-based transmitter compliance measurements
require filtered responses. The 86100C offers a broad range of
filter combinations. Filters can be automatically and repeatably
switched in or out of the measurement channel remotely over
GPIB or with a front panel button. The frequency response of
the entire measurement path is calibrated, and will maintain
its performance over long-term usage.
• The integrated optical receiver provides a calibrated optical
channel. With the accurate optical receiver built into the
module, optical signals are accurately measured and displayed
in optical power units.
• Switches or couplers are not required for an average power
measurement. Signal routing is simplified and signal strength
is maintained.
