Pattern Generator

On a per-channel basis, you can programmatically configure channels to

drive data to your DUT through the same flying-lead cable. You can use

any set of channels for pattern generation at the same time you use

another set of channels to acquire data. NI 6552 bundles are capable of

switching between generation and analysis on a per-cycle basis. The

digital instruments have 32 MB of onboard memory for the acquired data

and a separate 32 MB of memory to store complex patterns for generation.

The NI Digital Waveform Editor provides an interactive tool for creating,

editing, and importing digital patterns. Once created, a pattern can be

configured to be output to your DUT with a single step in NI SignalExpress.

Data Analysis and Logging

The PC-based implementation means that, unlike traditional logic analyzers,

the full power of the computer is readily available to perform complex

analysis, data logging, and report generation. With SignalExpress, you can

easily export the captured data to file and save images of the captured

waveforms for easy report generation. Using National Instruments

LabVIEW, you can create custom analysis steps to plug into SignalExpress

to best match application needs.

Stimulus Response

The generation and acquisition capabilities of these instruments make

them ideal for stimulus-response applications. NI 6542 bundles can drive

data on one set of channels while simultaneously analyzing the response

data on the remaining channels. NI 6552 bundles offer more advanced

features, including per-cycle tristate and real-time hardware comparison.

With per-cycle tristate, you can switch from analyzing data to generating

data on a per-channel, per-clock-cycle basis. Real-time hardware

comparison checks the acquired data against the known expected

response for errors at the full clock rate of the digital instrument.

External Control

The digital waveform generator/analyzers included in the NI 6542 and

NI 6552 bundles offer a number of options for controlling the generation

and acquisition capabilities with external signals. Along with the ability to

import a sample clock or export the internal clock, four general-purpose

I/O lines are available for receiving external triggers or for generating

events, such as the Data Active Event, for handshaking with the DUT.

Using triggers and the linking and looping (scripting) features of the

board, you can dynamically control the waveforms generated and the

length of generation.

Mixed-Signal System in SignalExpress

SignalExpress not only includes digital analysis, acquisition, and

generation capabilities, but it also provides a range of instrument control

options for integrating other PCI, PXI, or stand-alone instruments into

a single system. You can program the complete system using the

interactive steps in SignalExpress. The shared architecture between the

digital instruments and many of the NI digitizers and arbitrary waveform

generators makes it easy to create a synchronized mixed-signal system.
