ADS1299EEG-FE Analysis Tools

Under the Analysis tab in the ADS1299EEG-FE GUI software, there are four different analysis tools

shown that enable a detailed examination of the signals selected by the front-end MUX:

•

Scope

•

Analysis

•

Histogram

•

FFT

These tools are detailed in the following subsections.

Using the Analysis

→Scope Tool

The Scope tool (available under the Analysis tab) is a very useful means of examining the exact amplitude

of the measured input signals from each channel. Additionally, users can determine the noise contribution

from each channel at a given resolution, and review the sampling rate, the PGA gain, and the input signal

amplitude. Figure 29 illustrates the Scope tool features.

Waveform Examination Tool

The waveform examination tool allows the user to zoom in either on all channels simultaneously or on a

single channel. Figure 30 shows an example of the waveform examination tool with the magnifying glass

zoomed in on 90 samples.
