This page describes the original BitScope design.

The BS300 and the later models are similar, the BS300 schematics are here.

The schematics below describe the main circuit. The next few pages walk you through the design. The sub-sections provide details of the analog circuits, A/D convertor and expansion POD.

This is the master BitScope schematic. All the following sheets show parts of this circuit in greater detail.
