Preliminary Technical Data
Connect the control board supplied mini plug to the 14V AC
source. Connect the evaluation board to the controller board
and connect the parallel port cable to the evaluation board and
to the PC. Proceed to the Software Installation section to install
the software.
SOFTWARE INSTALLATION
This section covers software installation for both versions of
capture boards; ECB only and CED. It is recommended to close
all Windows’ applications prior to installing the software.
System Requirements
CD-ROM –Double click on setup.exe and follow the instructions
on the screen.
Website Download
After downloading the software, it is recommended to use the
WinZip “Extract” function to extract all of the necessary
components as opposed to just clicking on setup.exe in the
zipped file. After extracting, click on seteup.exe in the folder
created during the extraction and follow the instructions on the
screen.
CED Version – (AD76xx Evaluation Software CED, Rev x.x)
The software will also install the necessary USB drivers. Note
that this version of software can be used for both CED and ECB
capture boards. When using the ECB capture board, the PC
must be rebooted. After installing the software, power up the
CED board and connect to the PC USB 2.0 port. The Windows
“Found New Hardware” Wizard will display. Click on Next to
install the drivers automatically.
• IEEE 1284 Compliant Parallel Port Cable (if not supplied)
• PC operating Windows 2000 or XP.
• USB 2.0 (for CED board)
• Bidirectional enhanced parallel port (for ECB board)
• Administrator privileges

When installed properly, Windows displays the following.
The “Device Manager” can be used to verify that the driver was
installed successfully.
ECB only Version (AD76xx Evaluation Software ECB, Rev x.x
After the software is finished installing, reboot the computer.
This driver will not take effect unless the computer is rebooted.
RUNNING THE SOFTWARE
This document covers both versions of software: CED and ECB
only. The evaluation board includes software for analyzing the
AD761X, AD762X, AD763X, AD764X, AD765X, AD766X,
AD767X, AD795X, AD67X and AD97x family. The EVAL-
CED1Z or EVAL-CONTROL-BRDXZ is required when using
the software. The software is used to perform the following
tests:
CED Version
Refer to Figure 11 to Figure 17 for further details and features of
the software. Currently the evaluation boards supported in this
version are limited to EVAL-AD76yyECBZ where yy = 21, 22,
23, 41,or 43.
• Histogram for determining code transition noise (DC)
• Fast Fourier transforms (FFT) for signal to noise ratio
• Decimation (digital filtering)
(SNR), SNR and distortion (SINAD), total harmonic
distortion (THD) and spurious free dynamic range (SFDR)
