High-Speed Digitizers – Optimized for Automated Test
For rapid initiation of an automated test sequence, use preconfigured
Express VIs to quickly set up your digitizer to immediately acquire data.
LabVIEW SignalExpress is an interactive environment you can use to
acquire, analyze, and log your data with no programming required.
Achieve Flexible Performance Using
NI Software-Defined Instrumentation
NI high-speed digitizers offer several advantages over traditional
stand-alone oscilloscopes by delivering an open architecture and
flexible software. With an NI digitizer, you can not only perform standard
oscilloscope measurements but also easily build other instruments such
as spectrum analyzers, transient recorders, and ultrasonic receivers. And
NI offers a comprehensive library in LabVIEW of prebuilt functions and
example programs geared at getting you up and running quickly.
Open Architecture: NI-SCOPE Driver and the
Application Programming Interface (API)
Using the full power of a PC-based measurement device requires the
ability to programmatically define and control its behavior. You can
programmatically control all NI digitizers using the NI-SCOPE instrument
driver, which provides:
• High-level functions for getting started quickly as well as low-level
control for accessing all the digitizer features
• More than 50 prewritten example programs that illustrate how to
access the full functionality of any NI digitizer
• Programming examples available for LabVIEW, C++, and Visual Basic

to immediately acquire data.
Flexible Software: Define Your Instrument
In an automated test environment, there are times when the ability to
quickly troubleshoot an issue is crucial. For those occasions, the NI-SCOPE
driver offers the measurement features and responsiveness of a
traditional benchtop oscilloscope through the NI-SCOPE Soft Front Panel
user interface. Take advantage of the more than 50 prebuilt measurement
and analysis functions included with the software.
While a quick signal check is valuable at times, other circumstances
may call for custom measurements. Stand-alone instrumentation,
such as dedicated oscilloscopes and spectrum analyzers, delivers
common functions that appeal to the needs of many engineers. As
you can imagine, these standard functions do not meet every application
need, particularly in automated test applications. But with LabVIEW
and the NI-SCOPE API, the digitizer that you use as a general-purpose
oscilloscope for one application can be used as a custom instrument
for more specialized measurements.

enabled through the combination of LabVIEW and NI modular instruments.

and responsiveness comparable to traditional benchtop oscilloscopes.
