Three Instruments in One

For basic oscilloscope operation there is easy front

panel access with that familiar analog-look and feel.

A Windows®-based system let’s you easily navigate

through the user-interface. The 86100A Infiniium DCA

can be viewed as three high-performance instruments

in one. It’s a general-purpose repetitive sampling oscil-

loscope. It’s a digital communications analyzer. It’s a

time domain reflectometer. Just select the instrument

mode and start making measurements.

Digital Communications Analysis

Accurate eye-diagram analysis is essential for charac-

terizing the quality of transmitters used from 100 Mb/s

to 40 Gb/s. The 86100A was designed specifically for

the complex task of analyzing 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

perform 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 improved accu-

racy and repeatability, and

• 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

86100A has a broad range of precision receivers inte-

grated 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 measure-

ments require filtered responses. The 86100A has 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 power

meter built into the module, optical signals are accu-

rately 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.

Eye Diagram Mask Testing

The 86100A provides efficient, high-throughput wave-

form compliance testing with a suite of standards

based eye-diagram masks. The test process has been

streamlined into a minimum number of keystrokes for

testing at industry standard data rates.

Standard Masks

• 1X Gigabit Ethernet

• 2X Gigabit Ethernet

• 10X Gigabit Ethernet

• Fibre Channel 0133

• Fibre Channel 0266

• Fibre Channel 1063

• Fibre Channel 2125

• STM0/OC1

• STM1/OC3

• STM4/OC12

• STM16/OC48

• STM64/OC192

• STS1 EYE

• STS3 EYE

Other eye-diagram masks are easily created through

scaling those listed above. In addition, mask editing

allows for new masks either by editing existing masks,

or creating new masks from scratch. The mask data

can be entered or modified on an external PC using a

text editor such as Notepad, then can be transferred to

the instrument’s hard drive using LAN or the A: drive.

Once in the instrument, the mask can be used for

mask test.

Perform these mask conformance tests with conve-

nient user-definable measurement conditions, such as

mask margins for guardband testing, number of wave-

forms tested, and stop/limit actions.

Measurement Speed

Measurement speed has been increased with both fast

hardware and a user-friendly instrument. In the lab,

don’t waste time trying to figure out how to make a
