Keysight Infiniium DCA Series Analyzers
12 models with full specifications from Keysight Technologies (Agilent HP).
The Keysight Technologies (formerly Agilent HP) Infiniium Digital Communications Analyzer (DCA) series is a modular platform built for high-speed digital design characterization, fiber optic testing, and time-domain reflectometry (TDR). This page covers the 86100-series mainframes—specifically the 86100A, 86100B, 86100C, and 86100D—alongside their compatible optical, electrical, and timebase modules. Designed for telecom, datacom, and high-speed electrical backplane testing, these systems provide precise waveform measurements, compliance eye-diagram analysis, and jitter characterization. By selecting the appropriate combination of mainframe and specialized plug-in module, engineering teams can configure a customized sampling oscilloscope tailored to their bandwidth, resolution, and channel-count requirements.

Mainframe Evolution and Digital Communication Analyzers
The Keysight Infiniium DCA family includes four generations of mainframes. The 86100A is a Windows-based, wide-bandwidth sampling oscilloscope that combines a repetitive sampling oscilloscope, a digital communications analyzer, and a time-domain reflectometer (TDR) into one system. It features an 8.4-inch touchscreen and a sample rate of up to 40 kSa/s. The 86100B shares the 8.4-inch display, adding built-in automated compliance testing and support for the 861xx, 83480A, and 54750A module families. Both instruments utilize a 14-bit vertical resolution.
The 86100C Infiniium DCA-J scales the interface to a 10.4-inch color TFT LCD touchscreen and runs on Windows XP Professional. It introduces advanced measurements such as crossing percentage, Q-factor, and pattern lock to view single-valued waveforms at high bit rates. The 86100D Infiniium DCA-X features a 10.4-inch XGA touchscreen and a Dual UI environment, allowing users to switch between the FlexDCA and DCA-J classic interfaces. It supports up to 64 simultaneous measurements and provides remote programming code compatibility with the 86100C.
Transceiver Test Modules
The 86105 series of plug-in modules offers integrated optical and electrical channels for characterization of transceivers. The 86105A provides selectable optical and electrical bandwidths of 12.4 GHz or 20 GHz, operating from 1000 nm to 1600 nm. The 86105B introduces a 15 GHz optical channel and a 20 GHz electrical channel with an electrical rise time of 17.5 ps at full bandwidth, operating across the 1000 nm to 1600 nm range.
For higher data rates, the 86105C module operates from 750 nm to 1600 nm, providing a 9 GHz unfiltered optical channel and up to 20 GHz electrical bandwidth. It is configured via Options 100, 200, or 300 to support rates up to 11.3 Gb/s. The 86105D module extends coverage to a 750 nm to 1650 nm wavelength range. Option 100 configures the module with a 20 GHz optical and 35 GHz electrical bandwidth, whereas Option 200 provides a 34 GHz optical and 50 GHz electrical bandwidth, achieving an electrical rise time of 7.0 ps.
Ultra-High Bandwidth and Special-Purpose Modules
For ultra-high-speed signaling, the 86116C module offers up to 70 GHz of optical bandwidth (Option 040) and 93 GHz of electrical bandwidth. It is designed with 1.0 mm male electrical inputs and is optimized for 40G SONET/SDH or 25G Ethernet measurements. To minimize cabling losses, the 86118A acts as a dual-channel remote electrical sampling head module with 1.0 mm female inputs and over 70 GHz of electrical bandwidth, placing the sampling electronics close to the device under test.
To expand channel density, the 86115D is a multi-port receiver module featuring dual optical channels and dual or quad electrical channels. For high-frequency timing accuracy, the 86107A Precision Timebase Reference Module interfaces with the 86100A/B/C mainframes. It operates over RF input frequencies up to 48 GHz (Option 040), yielding typical timebase resolution down to 2 ps and reducing RMS jitter to less than 200 fs for input frequencies above 4 GHz.
Frequently asked questions
- Can previous generation DCA modules be used with the 86100D mainframe?
- Yes, the 86100D Infiniium DCA-X mainframe is 100% backwards compatible with all previous DCA modules. It also maintains 100% remote programming code compatibility with the 86100C mainframe.
- What options are available to reduce timebase jitter on the Infiniium DCA mainframes?
- For the 86100D mainframe, Option PTB provides an integrated precision timebase with typical jitter of < 50 fs rms (< 100 fs rms maximum). For the 86100A, 86100B, and 86100C mainframes, the external 86107A Precision Timebase Reference Module can be added to provide ultra-low jitter of less than 200 fs rms for frequencies greater than 4 GHz.
- What is the benefit of the 86118A remote sampling head module over standard plug-in modules?
- The 86118A remote electrical sampling head module places the sampling electronics directly inside two small, lightweight heads rather than inside the mainframe. With over 70 GHz electrical bandwidth per channel, this setup minimizes cabling losses and improves signal fidelity near the device under test.
