The ADInstruments PowerLab/16SP is a 16-channel data acquisition unit designed for life science research requiring high-fidelity physiological signal recording. The system captures biological data across neurophysiology, sleep studies, and isolated tissue applications with 16-bit resolution and continuous disk recording at up to 200,000 samples per second (400,000 samples per second aggregate). Its single-ended analog inputs accept 12 selectable full-scale ranges from ±2 mV to ±10 V, enabling precise measurement of both small and large amplitude signals. AC or DC coupling and wide-range low-pass filtering accommodate diverse signal conditioning requirements. The PowerLab/16SP connects via High Speed USB 2.0 or SCSI interfaces and includes two independent stimulator outputs, external trigger input, digital I/O for instrument control, and an I2C expansion port supporting up to 16 additional Front-end channels at communication rates to 10,000 bits/s. Pod (DIN) connectors provide alternative input paths for signal conditioning integration. The unit pairs directly with ADInstruments LabChart and Scope software platforms for data analysis and experimental control.
