ADS1299EEG-FE Analysis Tools
6 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.
6.1 Scope Tab
6.1.1 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.

6.1.2 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.
