EVALUATION BOARD SOFTWARE QUICK START PROCEDURES

This section provides quick start procedures for using the AD9276
and AD9277, either on the evaluation board or at the system
level design. Both the default and optional settings are described.

CONFIGURING THE BOARD FOR TGC MODE

Before using the software for testing, configure the evaluation
board as follows:
1. Connect the evaluation board and the HSC-ADC-EVALCZ
as shown in Figure 1 and Figure 2.
2. Connect one 6 V, 2.5 A switching power supply (such as
the CUI, Inc., EPS060250UH-PHP-SZ supplied) to the
evaluation board.
3. Connect one 6 V, 2.5 A switching power supply (such as
the CUI EPS060250UH-PHP-SZ supplied) to the HSC-
ADC-EVALCZ board.
4. Connect the USB cable to J6 on the HSC-ADC-EVALCZ
board to the PC.
5. On the evaluation board, place jumpers on all five pin pairs
of J404 to connect the SPI bus.
6. On the evaluation board, ensure that J501 (OSC_EN) is
jumpered to the OFF setting to use the on-board 40 MHz
Valpey Fisher VFAC3 oscillator.
7. On the evaluation board, use a clean signal generator with
low phase noise to provide an input signal to the desired
channel. 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

Set Up the ADC Data Capture Block
After configuring the evaluation board, set up the ADC data
capture block using the following steps:
1. Open VisualAnalog™ on a PC. AD9276 or AD9277 should
be listed in the status bar of the New Canvas window.
Select the template that corresponds to the type of testing
to be performed (see Figure 3).

2. After the template is selected, a message box opens, asking
if the default configuration can be used to program the
FPGA (see Figure 4). Click Yes, and the window closes.
If a different program is desired, follow Step 3.

3. To view different channels or change features to settings
other than the default settings, click the Expand Display
button located on the top right corner of the VisualAnalog
window, as shown in Figure 5 and Figure 6.
This process is described in the
VisualAnalog Converter Evaluation Tool Version 1.0 User
Manual. After you are finished, click the Collapse Display
button.
