12-19Probe AdaptersProbe AdaptersAdapters OverviewEach TDT headstage is designed for use with a particular style of probe. Probeadapters allow each headstage to be used with a wider variety of probes. Whenusing adapters, keep in mind that standard operation (differential vs single ended)varies for acute and chronic preparations and headstages are designed accordingly.When adapting across preparations, carefully note and understand the use of theground (G) and reference (R) connections provided on each adapter.AC‐CH Acute Headstage to Chronic Probe (16Channels)The AC-CH adapter allows the user to connect a 16-channel chronic probe (suchas a TDT 16 channel microwire array) to an acute TDT headstage (RA16AC/RA16AC4). Standard operation for chronic preparations is single ended with groundand reference shorted together in the chronic headstage. However, the acuteheadstage is designed for differential operation. When using the acute headstage withour microwire arrays, short G and R together on the adapter for single endedoperation.Pinouts are looking into the connector and reflect the preamplifier channels.TDT probe adapters are designed for specific TDT headstage to probe connections.
