Getting Started

This section provides quick start procedures for using the AD9680-1000EBZ board.

Configuring the Board

Before using the software for testing, configure the evaluation board as follows Connect the AD9680-1000EBZ evaluation board to the ADS7-V1EBZ data capture board, as shown
in Figure Connect one 12V, 6.5A switching power supply such as the CENB1080A1251F01 supplied to P4 on
the supplied USB cable. Turn on the ADS7-V1EBZ. The ADS7-V1EBZ will appear in the Device Manager as shown in Figure
