Single Headstage Configurations
Multiple Headstage Configurations
Note: All headstages must use the same Ground wire. But not all headstages need to use
the same Reference wire.
Headstage Connection Guide
Single Headstage with a Shared
Ground and Reference
When using a single headstage with a shared
ground and reference, the ground and reference
pins of the headstage should be tied together. A
ground is used and attached to a skull screw. All
recordings will reference this connection. This
configuration is referred to as "Single-Ended".
Single Headstage with a Separate
Ground and Reference
When using a single electrode with a separate
ground and reference, it is important that the
headstage itself is not single-ended, that is, its
ground and reference pins are NOT tied together.
This will allow the headstage to reference each
channel to ground as well as an additional chosen
site on the subject. This configuration is referred to
as "Differential"
Multiple Headstages with a
Shared Ground or Reference
When using multiple headstages with a
shared ground or reference, the ground and
reference pins of each headstage should be
tied together. A ground is used and attached
to a skull screw. This ground is used by all
headstages and ensures the headstages are
referencing the same potential. This is a
multiple single-ended configuration.
