miniLAB 1008 User's Guide

Functional

Details

Since the data is acquired at a rate faster than it can be transferred to the host, burst scans
are limited to the depth of the on-board memory. As with continuous mode, the
maximum sampling rate is an aggregate rate. Consequently, the maximum burst mode
rates are 8 kS/s, 4 kS/s and 2 kS/s for one, two and four channels, respectively.

External components

The miniLAB 1008 has the following external components, as shown in Figure 4-1.

USB connector

Status LED

Digital I/O connector

Screw terminal banks (2)
