Chapter 1 Introduction To improve timing resolution for repetitive signals, you can use random interleaved sampling (RIS) on your NI 5102. This method of sampling allows you to view pretrigger data and achieve an effective sampling rate as high as 1 GS/s, 50 times the real-time sampling rate of the device. Detailed specifications of the NI 5102 devices are in Appendix A, Specifications. Acquiring Data with Your NI 5102 You can acquire data either programmatically by writing an application for yo

Chapter 1 Introduction NI-SCOPE Driver The NI-SCOPE driver is the preferred choice to program your NI 5102. It provides flexibility and programmability in a standard full-featured instrument-driver format which lets you avoid low-level software calls and which works with LabVIEW, LabWindows/CVI, and conventional languages such as C/C++ and Visual Basic. To help you get started, NI-SCOPE comes with examples you can use or modify. You can find examples for these different ADEs: LabVIEW— Go toPro

Chapter 1 Introduction Note NI 5102 digitizers use only the easy I/O interface under data acquisition in LabWindows/CVI. The easy I/O interface provides limited functionality in CVI. To use the NI 5102 to its full capabilities, use the NI-SCOPE driver as shown in Figure 1-1. Measurement Studio contains tools for data acquisition and device control built on NI-DAQ driver software. Measurement Studio provides a higher-level programming interface for building virtual instruments with Visual Basic,

Chapter 1 Introduction PXI-specific features, RTSI bus trigger, RTSI Clock, and Serial Communication are implemented on the J2 connector of the CompactPCI bus. Table 1-1 lists the J2 pins used by your NI 5102 (PXI) digitizer, which is compatible with any CompactPCI chassis with a sub-bus that does not drive these lines. Even if the sub-bus is capable of driving these lines, the NI 5102 (PXI) is still compatible as long as those pins on the sub-bus are disabled by default and are never enabled. D

3 Digitizer Basics This chapter explains basic information about using digitizers, including important terminology and use of the probe. Understanding Digitizers To understand how digitizers work, you should be familiar with the Nyquist theorem and how it affects analog bandwidth and sample rate. You should also understand vertical sensitivity, analog-to-digital converter (ADC) resolution, record length, and triggering options. Nyquist Theorem The Nyquist theorem states that a signal must be sam
