Circuit Lake

Let’s build a simple digital oscilloscope.

• Single channel 100MHz/100MSPS (100 mega-samples-per-second)
• RS-232 based (we’ll look into USB too)
• Inexpensive!

A simple digital oscilloscope recipe

Using parts from KNJN.com, here are the basic items of our recipe.

• 1 x Pluto FPGA board, with TXDI and cable (item#1121, $39.95)
• 1 x Flash acquisition board (item#1205, $39.95)
• 1 x BNC (item#1250, $4.95)
• 1 x Nylon standoffs (item#1270, $0.95)
• 1 x Male/female connectors 2×8 (item#1275, $2.95)

That’s about $88.75 so far. link
