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.
