You see that there are no stimulus artifacts visible on almost all non-stimulating electrodes,
with some residual artifacts on the neighbor electrodes of the stimulating electrode 33.
In this example, we have used a Wait of 200 μs.
Wait settings
You can use the Wait for optimizing the electrode's behavior. The Wait parameter is the delay
between switching the electrodes from stimulation back to recording, that is, the stimulating
electrodes are disconnected from the stimulus input at the end of the trigger signal, and all
electrodes are connected to the amplifier input at the end of the Wait period.
The Wait helps avoiding cross-talk between stimulating and non-stimulating electrodes as well as
preventing switch artifacts.
The length of the Wait depends on several factors (electrode performance, stimulus amplitude,
for example) and has to be optimized empirically for each experimental setup.
 Enter increasing Wait values and monitor the performance of the stimulus artifact suppression.
