National Instruments PXI-6551 / PXI-6552 Digital Waveform Generator
Features

• -2.0 to 5.5 V Programmable Voltage Levels in 10 mV Steps
• 20 Channels with Per-Cycle, Per-Channel Bidirectional Control
• Real-Time Hardware Comparison of Acquired Response Data

The National Instruments PXI-6551/PXI-6552 are 50 and 100 MHz digital waveform generator/analyzers, respectively, for characterizing, validating, and testing digital electronics. The voltage levels on these devices can be programed with 10mV resolution. The PXI-6551/PXI-6552 modules feature 20 channels with per-channel, per-cycle direction control deep onboard memory with triggering and pattern sequencing.

The PXI-6551/PXI-6552, used for building high-performance stimulus-response systems, include:
– Programmable voltage levels for testing multiple devices or characterizing a single device under changing conditions
– A versatile memory architecture for maximum flexibility of waveform and scripting memory
– Per-cycle tristate for bidirectional communication
– A sophisticated timing engine to adjust for the timing parameters of the device under test

The PXI-6551/PXI-6552 can be used with the NI Digital Waveform Editor. These modules, used with the SMC, can create arbitrary waveform generators, mixed-signal test systems with digitizers, and other digital waveform generators/analyzers. It can also synchronize multiple digital waveform devices to build high-channel-count test systems.
