NI 655x Selection Guide Overview The National Instruments 6552 and 6551 are 100 and 50 MHz digital Mixed-signal design validation and test waveform generator/analyzers, Interfacing to digital electronics respectively, for characterizing, Aerospace/Defense validating, and testing digital Subsystem emulation Bit error rate tester (BERT) electronics. These modules feature Communications 20 channels with per-channel, Multimedia chipset emulation per-cycle direction control and deep Consumer Electronics onboard memory with triggering and CMOS and CCD imaging sensors pattern sequencing. You can program Digital display tests the voltage levels on NI 655x devices with 10 mV resolution. You can use them with the NI Digital Waveform Editor, an interactive software tool for creating, editing, and importing digital waveforms. With the SMC, you can create mixed-signal test systems with digitizers, arbitrary waveform generators, and other digital waveform generator/analyzers, or you can synchronize multiple digital waveform devices to build high-channel-count test systems. Applications Semiconductor Design High-Performance Tests For building high-performance stimulus-response systems, the NI 655x devices include: • A sophisticated timing engine to adjust for the timing parameters of the device under test • Programmable voltage levels for testing multiple devices or characterizing a single device under changing conditions • Per-cycle tristate for bidirectional communication • A versatile memory architecture for maximum flexibility of waveform and scripting memory The hardware architecture is designed to preserve high signal quality, and an eye diagram of the PXI-6552 generation is shown in Figure 1. You can use the internal clock or an external clock, such as from the NI PXI-5404, through the front panel. You can also shift the data generated, data acquired, and exported sample clock relative to the onboard clock for clock frequencies above 25 MHz, which is critical to adjust for propagation delays and setup-and-hold times in the device under test. Programmable voltage levels are needed when testing different devices or when characterizing how a given device performs under changing conditions. With NI 655x devices, the high and low levels for 100 and 50 MHz, Programmable-Voltage Digital Waveform Generator/Analyzers acquisition and generation can be set independently. You can program the voltage levels between -2.0 and 5.5 V with 10 mV resolution for TTL, LVTTL, LVCMOS, ECL, PECL, and other signal level compatibility. The SMC memory architecture is designed for maximum flexibility between waveform memory and scripting memory, the instructions for pattern linking and looping. Using a single memory bank, you can allocate as much memory as needed for script and waveform data, giving you maximum flexibility from test to test. Driver Software NI 655x devices include the NI-HSDIO driver with an intuitive, powerful API based on IVI guidelines. The Windows-compatible NI-HSDIO driver provides an API for LabVIEW, SignalExpress, LabWindows/CVI, and other text-based development environments. Figure 1. Eye Diagram of NI PXI-6552 Generation Create Digital Waveforms Interactively with the Digital Waveform Editor With the NI Digital Waveform Editor, an interactive software tool for creating and editing digital waveforms, you can import existing test patterns from popular spreadsheet and VHDL simulation packages in ASCII or value change dump (VCD) formats. Once imported, you can view the waveforms graphically and edit them interactively for new devices or new test conditions. You can also build new waveforms with built-in fill patterns such as pseudorandom bit sequences (PRBS) and count up/down patterns. When ready to test your device, the waveforms import seamlessly into NI LabVIEW, SignalExpress, and C. The Digital Waveform Editor is included with the 8 and 64 Mb/channel memory models, and is a separate add-on for use with the 1 Mb/channel model. Figure 2.

For tight timing requirements, these PXI modules phase-lock to the 10 MHz reference clock on the PXI backplane. If you have an external precision reference, you can import it through the front panel SMB connector. BUY NOW!
