EVALUATION BOARD SOFTWARE QUICK START PROCEDURES
This section provides quick start procedures for using the AD9434
and AD9484 evaluation board. Both the default and optional
settings are described.
CONFIGURING THE BOARD
Before using the software for testing, configure the evaluation
board as follows:
1. Connect the AD9434 evaluation board to the HSC-ADC-
EVALCZ boards as shown in Figure 1.
2. Connect one 6 V, 2 A switching power supply (such as the
CUI EPS060250UH-PHP-SZ supplied) to the AD9434
board.
3. Connect one 5 V, 3 A (6 V, 2 A can optionally be used)
switching power supply (such as the CUI
KSAFD0500300W1US supplied) to the HSC-ADC-
EVALCZ board.
4. Connect the HSC-ADC-EVALCZ board to the PC with a
USB cable. (Connect to J6.)
5. On the ADC evaluation board, make sure that jumpers are
on the J300 to J303 headers to connect the power supplies.
Connect Pin 1 to Pin 2 of P200 and Pin 2 to Pin 3 of P400
to connect the SPI bus to the ADC.
6. On the ADC evaluation board, provide a clean, low jitter
clock source to connector J200 at the desired ADC
conversion rate.
7. On the ADC evaluation board, use a clean signal generator
with low phase noise to provide an input signal at the J100
connector. Use a 1 meter, shielded, RG-58, 50 Ω coaxial
cable to connect the signal generator. For best results, use a
narrow-band, band-pass filter with 50 Ω terminations and
an appropriate center frequency. (Analog Devices uses
TTE, Allen Avionics, and K&L band-pass filters.)
USING THE SOFTWARE FOR TESTING
Setting Up the ADC Data Capture
After configuring the board, set up the ADC data capture using
the following steps:
1. Open VisualAnalog® on the connected PC. The appropriate
part type should be listed in the status bar of the
VisualAnalog – New Canvas window. Select the template
that corresponds to the type of testing to be performed
(see Figure 5 where the AD9434 is shown as an example).

2. After the template is selected, a message appears asking if
the default configuration can be used to program the FPGA
(see Figure 6). Click Ye s , and the window closes.

3. To change features to settings other than the default
settings, click the Expand Display button, located on the
bottom right corner of the VisualAnalog window, to see
what is shown in Figure 8.
4. Detailed instructions for changing the features and capture
settings can be found in the AN-905 Application Note,
VisualAnalog Converter Evaluation Tool Version 1.0 User
Manual. After the changes are made to the capture settings,
click Collapse Display (see Figure 7).
