Channel Inputs Connected
It may sometimes be required to provide a calibration or test signal to ADS1299 device with the positive
input connected to the pin or electrode. This can be accomplished by connecting the positive test signal to
SRB2 pin and the negative test signal to SRB1 pin. The channel input multiplexer must be set for Normal
Electrode (000), SRB2 switch must be closed and SRB1 switch must be closed. This multiplexer setting is
illustrated in Figure 48.
