Pinnacle's three-channel tethered systems provide a cost-effective solution for researchers who prefer recording in a fixed EEG/EMG configuration. The data conditioning and acquisition system (DCAS) and preamplifier are preconfigured and ordered as a matching pair. Standard configurations include 2 EEG/1 EMG and 3 EEG; custom configurations are available upon request.

Pinnacle's hardware kits include a data conditioning and acquisition unit, preamplifier, commutator, mounting plate, free acquisition software, and step-by-step manual guides. Mouse and rat configurations are shown in the tables below. Hardware systems have fixed high pass and gain setting base on field of research. For more information see our preamplified systems below.

For new users of our systems, Pinnacle recommends the purchase of an accessory kit for use with the three-channel hardware system. Kits include all necessary one-time purchases, such as testing equipment and enough surgical supplies to complete initial surgeries. Disposable items can also be ordered individually.

DATA CONDITIONING AND ACQUISITION SYSTEM

The data conditioning and acquisition system (DCAS) performs secondary amplification and filtering before sending data to Pinnacle's Sirenia® Acquisition software for collection via a USB cable.

3 channels 16-bit resolution User-selectable gain: 5,000 - 100,000 V/V Adjustable sampling rates: 200 - 2000 Hz Software configurable low-pass filters: 11 Hz - 1000 Hz High-pass filters: 0.5 Hz EEG, 10 Hz EMG for sleep; 1.0 Hz EEG for seizure 4 TTL input/outputs

Pinnacle's commutators provide excellent freedom of movement while maintaining clean and constant electrical signals. Custom modifications are also available for use with third-party cabling and connection schemes.

MOUSE COMMUTATOR A low-torque commutator (< 2 x 10-4 N-m), mounted above the cage, allows for unencumbered freedom of movement. A 7-inch cable extends from the commutator.		RAT COMMUTATOR A P1 commutator is mounted above the cage. The commutator's two-plug setup allows for even rotation of the rotor.

Signals are amplified and filtered at the head of the animal using our preamplifiers, which ensure the delivery of clean, artifact free data. Have your own amplification or acquisition system? Our analog adapters can be used to connect Pinnacle's preamplifiers with third-party data collection systems.

Pinnacle's preamplifiers provide differential amplification (x10 or x100) between electrodes. Our standard three and four-channel preamplifiers have two referential channels and one or two differential channels. Fully referential and fully differential versions are also available.

MOUSE PREAMPLIFIERS Preamplifiers amplify and filter signals at the head for clean, artifact-free data. The commutator connects to the preamplifier’s 7-inch cable, made of six insulated, lightweight wires. The mouse preamplifier attaches to the headmount via a friction fit.		RAT PREAMPLIFIERS Preamplifiers amplify and filter signals at the head, ensuring clean, artifact-free data. A 17.5-inch cable, protected by a metal spring coil, connects the preamplifier to the commutator. A P1 Technologies screw connector secures the preamplifier to the animal’s head.
