Description
Create and Edit Patterns Interactively
The National Instruments 6542 and 6541 devices are 100 and 50 MHz with the Digital Waveform Editor
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
•
Import existing waveforms into LabVIEW from VHDL simulation and
spreadsheet tools in Value Change Dump (.VCD) or ꢀSCII formats
Create new waveforms using built-in fill patterns
•
•
Edit waveforms interactively in the user interface
interface with 5.0, 3.3, 2.5, or 1.8 V logic. You can also use these devices • Link and loop created digital waveforms with the Script Editor
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.
