To operate the device under test (DUT) using the SPI, follow the jumper settings for P1 as shown in
Table 1.

How To Use The Software For Testing

Setting up the ADC Data Capture

The installers for VisualAnalog and SPIController are in the following locations:

ftp://ftp.analog.com/pub/HSSP_SW/VisualAnalog/VisualAnalog_Setup.exe
ftp://ftp.analog.com/pub/adispi/A2DComponents/Install/SPIController_Setup.exe

Run these installers on the PC that is connected to the evaluation setup before proceeding.

After configuring the board hardware, set up the ADC data capture using the following steps:

Start VisualAnalog on the connected PC. The appropriate part type should be listed in the status

1.

bar of the VisualAnalog – New Canvas window. Select the template that corresponds to the type
of testing to be performed (see Figure 3).
