Note: In the following sections, software-related items

are identified by bolding. Text in bold refers to items

directly from the EV kit software. Text in bold and under-

lined refers to items from the Windows operating system.

Procedure

The EV kit is fully assembled and tested. Follow the

steps below to verify board operation. Caution: Do not

turn on the power supply until all connections are

completed.

1) Uncompress the 11103Rxx.ZIP file in a temporary

folder.

2) Install the EV kit software on your computer by run-

ning the INSTALL.EXE program inside the tempo-

rary folder. The program files are copied to your PC

and icons are created in the Windows All Programs

menu. During software installation, some versions

of Windows may show a warning message indicat-

ing that this software is from an unknown publisher.

This is not an error condition and it is safe to pro-

ceed with installation. Administrator privileges are

required to install the software on Windows.

3) Verify that all jumpers are in their default positions,

as shown in Table 1.

4) Connect the positive terminal of the 5.5V power

supply to the VIN connector on the board. Connect

the negative terminal of the same power supply to

the GND connector on the board.

5) Set the signal source to generate a 100kHz, 1V

peak-to-peak sinusoidal wave with 2V offset.

6) Connect the positive terminal of the signal gen-

erator to the AIN1_DC or AIN1_DC_SMA connector.

Connect the negative terminal of the signal genera-

tor to the GND connector.

7) Turn on the power supply.

8) Turn on the function generator.

9) Connect the USB cable from the PC to the

EV kit board. Follow the instructions on the

SLS_USB_Driver_Help_100.PDF file to manually

install the USB driver. Administrator privileges are

required to install the USB device driver on Windows.

10) Start the EV kit software by opening its icon in the

Windows All Programs menu. The EV kit software

main window appears, as shown in Figure 1.

11) The main window should display Hardware

Connected at the bottom-left corner

12) Check the Remove DC checkbox.

13) Press the Start Conversion button.

14) Verify that the Frequency displayed in the Calculation

group box reads approximately 100000Hz.

Detailed Description of Software

The main window of the evaluation software

(Figure 1) contains a Device Configuration group box,

a Datalogging group box, and four tab sheets to display

the sampled data.

Device Configuration

Use the Channel Select drop-down list in the Device

Configuration group box to select the analog input

channel for analog-to-digital conversion.

Data Logging

In the Datalogging group box, the user can select

the desired number of conversions in the Number of

Samples drop-down list. Enter the desired sampling rate

in the Sample Rate (ksps) edit box. The actual sampling

rate is displayed at the right of the Sample Rate (ksps)

edit box. Press the Start Conversion button to start

sampling. After sampling is finished, the user can save

the data to a file by pressing the Save to File button.

The Save to File button is not active until the sampling

is done.

Time Domain, Frequency Domain,

Histogram, and Single Conversion Tabs

After the Start Conversion button in the Datalogging

group box is pressed, the sampled data in the time

domain is plotted in the Time Domain tab sheet. The

sampled data in the frequency domain is plotted in the

Frequency Domain tab sheet, and the histogram of the

sampled signal is plotted in the Histogram tab sheet.
