Using the ADS1298ECG-FE Software

3 - FFT Analysis

Pressing the FFT Analysis button pulls up the FFT Analysis window shown in Figure 24. This window

provides calculated parameters obtained from the collected data that may be useful during evaluation.

One of the values included in this analysis is the channel-to-channel noise.

4 - User-Defined Dynamic Range

This section enables the user to examine the SNR of a specific channel within a given frequency band

defined by Low Frequency and High Frequency. The SNR displayed in this window shows under the

Dynamic Range heading as Figure 25 illustrates.

5 - Input Amplitude

This field is a user input that is important for accurately calculating the CMRR of each channel.

6 - Zoom Tool

As with the Analysis, Histogram, and Scope tool, this zoom function allows a closer examination of the

FFT at frequencies of interest, as shown in Figure 26.
