The CDBCapture+ board and software currently

support the following Crystal A/D converter eval-

uation boards:

Data Acquisition Parts via a dual row 10 position

header interface:

Audio Parts via RCA phono jack and optical inputs

for S/PDIF audio data (for sample rates from 30

KHz to 96 KHz):

Future products will be added with software up-

dates.

Software updates are provided with the

Crystal Product Guide CD-ROM and on the Crys-

tal Website at www.crystal.com.

Packaging List:

CDBCapture+ Interface Board

Serial 10 position ribbon cable connector

RS232 Cable

Note: To use the S/PDIF interface, a phono-jack

cable must be purchased from an outside vendor.

The Capture+ evaluation software is installed using

the setup utility provided on the Product Guide CD-

ROM. The location for installation may be any

drive/directory. README and HELP text files are

provided and offer step-by-step instructions on set-

ting up and operating both the hardware and soft-

ware as well as providing information specific to

each supported evaluation board. Once the soft-

ware is installed and launched, the Startup Screen

is displayed on the monitor, as shown in Figure 2.

Pressing the "OK" button starts the software that al-

lows the user to setup the serial port between the

Capture+ module and the PC and configure the

module for a specific A/D converter.

Screens

showing the variety of analysis functions that can

be utilized for evaluation of an A/D converter are

shown and described below.

A Time Domain Analysis is initiated by connecting

a signal source to the evaluation board and acquir-

ing a user-selectable number of samples. The re-

sults of capturing a sine wave are shown in

Figure 3. A reconstruction of the data samples is

displayed, along with the sample count on the hor-

izontal axis and magnitude (A/D counts) on the
