The Measurement Computing MiniLAB 1008 is a USB-powered multifunction data acquisition device delivering analog input/output, digital I/O, and counter/timer functionality in a compact form factor. It acquires data at up to 100 kS/s aggregate throughput with 12-bit resolution across eight single-ended analog input channels, two analog outputs, eight programmable digital I/O lines, and one 32-bit counter/timer. The unit operates over software-selectable voltage ranges from ±10 V down to ±1.25 V (analog input) and 0-10 V or 0-5 V (analog output), with input protection to ±15 V and TTL-compatible digital logic. Triggering options include software, digital input, and external trigger modes, enabling flexible data capture strategies. All connections use screw terminals for sensors, actuators, and counter signals, with USB Type B connectivity for power and communication. Operating temperature range spans 0 °C to 55 °C.
