8. Programming the Digital Waveform
Generator/Analyzer
You can generate or acquire digital data with the NI digital waveform
generator/analyzer using NI-HSDIO. You also can run the NI-HSDIO
examples to demonstrate the functionality of your device.
NI-HSDIO Instrument Driver
The NI-HSDIO API features a set of operations and attributes that exercise
all the functionality of the device, including configuration, control, and other
device-specific functions.
Information about programming with NI-HSDIO is available in the
NI Digital Waveform Generator/Analyzer Help. This online document
contains hardware information, concepts, a detailed function/VI reference
for NI-HSDIO, and information specific to your device.
NI-HSDIO Examples
The NI-HSDIO examples demonstrate some of the functionality of the
NI digital waveform generator/analyzers that you can use or integrate into
your applications.
For the location of example programs that you can use as a basis for your
first NI-HSDIO program, refer to Programming»Getting Started with
NI-HSDIO in the NI Digital Waveform Generator/Analyzer Help.
Appendix A: Device Front Panels
This section contains front panel connector figures and connector description
tables that describe the signal connection options for NI digital waveform
generator/analyzers.
NI 654X/655X Front Panels and Connectors
The NI 654X/655X front panels contain four connectors—three SMB jacks
(CLK IN, PFI 0, and CLK OUT) and one 68-pin VHDCI connector
(DIGITAL DATA & CONTROL, or DDC).
Figure 8 shows the NI 6541 front panels and pinout, which are identical to
those of the NI 6542. The DDC signals are described in Table 4. The
SMB connectors are described in Table 7. The LEDs are described in
Tables 8 and 9.
