5.7.1 Patient Simulator Input

The output from any typical patient simulator can be directly fed into the DB15 connector (J1). For all measurements in this user guide, a Fluke medSim 300B simulator was used as the ECG signal source (Figure 37) . The simulator is capable of generating ECG signals down to 50µV of amplitude. Particular attention must be given to the common-mode value of the input signal for proper data capture. Refer to the ADS1298 product data sheet or ADS1198 product data sheet for the common-mode range for various programmable gain amplifier (PGA) gain settings. Section 4.4.1 explains the process used to capture 12-lead ECG data.
