If using electrodes to measure EDA on an equivalent sensor, the
leads on the custom ECG cable provided are as in Figure 29.

Electrocardiogram
An electrocardiogram (ECG) is a measure of how the electrical
activity of the heart changes over time as action potentials
propagate throughout the heart during each cardiac cycle.
Typically, the ECG is measured from the surface of the skin,
which can be done by placing electrodes directly on the skin
and reading the potential difference between them.
The AD5940 evaluation kit comes equipped with custom ECG
cables. These can be used with four wearable electrodes to

measure ECG rate on a sensor/ECG simulator. The ECG cables
are labeled in Figure 30.

The ECG cables are marked on block diagrams as E1, E2, E3,
and E4. The cable connections are as follows:
•
E1 = F+ = red
•
E2 = S+ = green
•
E3 = S− = blue
•
E4 = F− = black
