Equipment Needed

Analog signal source and antialiasing filter
Sample clock source (if not using the on-board oscillator)
Two switching power supplies (6.0V, 2.5A), CUI EPS060250UH-PHP-SZ provided
PC running Windows®
USB 2.0 port
AD9257-65EBZ or AD9637-80EBZ
HSC-ADC-EVALCZ FPGA-based data capture kit

Getting Started

This section provides quick start procedures for using the
Both the default and optional ADC settings are described.
Configuring the Board
Before using the software for testing, configure the evaluation board as follows:
1. Connect the evaluation board to the data capture board, as shown in Figure 1.
2. Connect one 6V, 2.5A switching power supply (such as the CUI, Inc., EPS060250UH-PHP-SZ that is
supplied) to the AD9257-65EBZ
3. Connect one 6V, 2.5A switching power supply (such as the supplied CUI EPS060250UH-PHP-SZ) to
the HSC-ADC-EVALCZ
4. Connect the HSC-ADC-EVALCZ
5. On the ADC evaluation board, confirm that the jumpers are installed as shown in Figure 2.
6. On the ADC evaluation board, use a clean signal generator with low phase noise to provide an
input signal to the desired channel(s). Use a shielded, RG-58, 50Ω coaxial cable (optimally 1 m or
shorter) to connect the signal generator. For best results, use a narrow-band, band-pass filter with
50Ω terminations and an appropriate center frequency. (Analog Devices, Inc. uses TTE, Allen
Avionics, and K&L band-pass filters.)
