XTR-BT V1.3
Specification
16 channel Bluetooth-linked
Electrophysiological Data
Streamer and Logger
General description
XTR-BT is a 16-channel electrophysiological data streamer and logger.
The main blocks of this device are:
- 16 single-ended low-noise amplifiers
- A Bluetooth transceiver
- A MicroSD memory card
- A microcontroller
The sixteen electro-physiological signal inputs connect via a 20-pin mini-card socket.
There are two grounding options:
- Multielectrode arrays with internal ground electrode via a 20-pin mini-card socket
- A standard commercial ground electrode vis DIN 42-802 to USB type C adapter
