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.
Power supply and serial interface circuits.
Logic Analyzer circuit.
Analog inputs, buffers and A/D convertor interface.
Vertical input channel buffer amplifiers.
If you have a PDF reader installed in your web browser, you can click on the thumbnails to see each schematic in detail.
You can also can download all five sheets in one zip file from our download area.
In addition to the main circuit, you can also view the schematics of our high speed A/D convertor.
and a circuit prototyping system called Proto POD
which connects to BitScope's Logic POD connector.
