4.4.1 Capturing 12-Lead ECG Signals

To capture signals from external inputs:

  1. Configure the Channel Input control in Globally Set Channels to Normal Electrode.
  2. Connect the 10 ECG electrodes from the Fluke simulator to the EVM through the DB15 connector (J1). Refer to Section A.5 for the ECG cable details. The ECG electrode signals are passed through a single pole RC filter followed by the lead configuration. For ECG signal processing, the electrode signals are routed through J5 to the ADS1298 input. The signal path in the board can be chosen by jumper settings, depending on the application.
