Reference the TSW1400 User’s Guide (

SLWU079

A) for more detailed explanations of the TSW1400 set-

up and operation. This document assumes the High Speed Data Converter Pro software and the
TSW1400 hardware are installed and functioning properly. This EVM requires High Speed Data Converter
Pro software version 2.09 with TSW1400 hardware of Rev D (or higher).

Single-tone FFT test (ADS4449 11-bit Operating Mode)

1. Start the High Speed Converter Pro GUI program.

When the program starts, select the ADC tab

and then select the ADS4449 device in the Select ADC menu.
