The AD9874’s evaluation board software and PCB board docu-
mentation comes on a CD-ROM titled,
AD9874 Evaluation Board
Software/Documentation
. The contents of the CD are as follows
and are placed in their associated folders:
•
Readme File (Readme.txt)
•
Eval Board Connectivity PDF File (interconnect_pcb.pdf)
•
Layout PDF File (ad9874cpcb.pdf)
•
Schematic PDF File (ad9874csch.pdf)
•
LabVIEW Eval_ File (ad9874_eval.exe ver. 5.1.1)
•
LabVIEW Eval_ Library File (ad9874_eval.llb ver. 5.1.1)
•
Installer Setup File for LabVIEW Run-Time Engine
(Setup.exe ver. 5.1.1)
The user has two options available in the installation and opera-
tion of the software. Before loading the software, the user should
verify that the NI 6533 DIO card and associated software has been
installed on to their PC. Option 1 is for users who currently
have LabVIEW version 5.1.1 loaded on their computer, while
Option 2 is for those who do not. Please select the appropriate
option and follow the recommended guidelines below.
Option1: Running the VIs from the library files (.llb) in LabVIEW:
a. Launch the LabVIEW application
b. Choose File, Open, and select the ad9874_eval.llb file in
the
Option1
subdirectory
c. From the File dialog box, choose the
ad9874_Eval_SW_090402. vi and click OK
Note, Analog Devices does not support modifications to any of
the VIs contained in the ad9874_eval library.
Option 2: Loading the run-time engine and running executable
files (.exe)
a. From Windows desktop environment, select START, run,
then browse to your cd drive, and execute the Setup.exe file
found in <cd drive letter>:
Option2\Installer\disks
directory.
Follow the instructions to load the run-time engine on
your computer.
b. From Windows desktop environment, select Start, run, then
browse to your cd drive and look for the ad9874_eval.exe files.
c. Hit Open to launch program.
Control Panel Description
Upon launching the AD9874_eval application, the control panel
shown in Figure 3 should appear. This panel is used to:
•
Configure and read back the various AD9874 SPI registers
•
Initiate a self-tuning macro for the AD9874’s ADC
•
Set the National Instruments data acquisition device’s
number
•
Access the demodulated complex I/Q signal or the ADC’s
undecimated data display windows.
The SPI registers are listed by their address and grouped accord-
ing to their function within the AD9874. When applicable, the
various control bits associated with some SPI register addresses
are expanded to further simplify programming of the IC. Lastly,
a Help button is available for each SPI register, providing a
more detailed description of its function.
