BioZ Drive Tab
This tab can configure four types of stimuli: a balanced square-wave source/sink current, a sine-wave
current, a sine-wave voltage, and an H-bridge voltage square wave. See the available options in Table 11
for more details.

Select I-Channel to Enable BioZ Measurement from the In-
Phase Component or Q-Channel to Enable BioZ
Measurement from the Quadrature-Phase Component.
Offers several modes of stimulation that can be selected:
Current for sine-wave current, Voltage for sine-wave voltage,
H-Bridge for square wave voltage, and Standby for a low-
power state where electrodes are driven to VMID_TX. Standby
is useful to maintain electrode bias between measurements.
Note that Current DAC Drive Mode is ignored when respiration
is enabled.
