Description
The National Instruments 6542 and 6541 devices are 100 and 50 MHz
digital waveform generator/analyzers, respectively, for interfacing to
digital electronics. These modules feature 32 channels with per-
channel direction control and deep onboard memory with triggering
and pattern sequencing. Through the NI-HSDIO driver, you can
interface with 5.0, 3.3, 2.5, or 1.8 V logic. You can also use these devices
with the NI Digital Waveform Editor, an interactive software tool for
creating and editing 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 devices to build low-skew multichannel
systems for interfacing to high pin count digital ICs and electronics.
Create and Edit Patterns Interactively
with the Digital Waveform Editor
• Import existing waveforms into LabVIEW from VHDL simulation and
spreadsheet tools in Value Change Dump (.VCD) or ASCII formats
• Create new waveforms using built-in fill patterns
• Edit waveforms interactively in the user interface
• Link and loop created digital waveforms with the Script Editor
