PCB ManufacturingĪll the design constrains are made in accordance to design capabilities of JLCPCB. If you are planning to build this use good resistors, they need to have tolerance under 1%. But I wanted something that is simple so I just used bunch of jumpers to switch between different reference resistors. Image taken from this Linkĭigilent also has a board that is made for inpedance analysis, it uses relays to switch between different reference resistors. ![]() This is based on the following block diagram, thanks to digilent. Now that Digilent has Impedance Analyzer feature on waveforms it only makes sense to design hardware to go along with it. You do lose the differential capability of scope channels when using this design, the oscilloscope negative channels are connected to Analog discovery ground. Both oscilloscope chanells have AC/DC coupling options as well as 50ohm support.Īfter probe compensation using a 1KHz square wave the signal integrity improved so much in comparision to wires flying everywhere. The 14bit resolution on Analog Discovery can do things that my actuall bench scope can never dream of. ![]() For a long time I was using the male headers for everthing, it was a mess. Having BNC connectors on Analog discovery makes a ton of sense, it is a scope after all. Link to Circuit Maker Workspace Description BNC Adapter This project was designed using Altium Circuit maker. Combined BNC Adapter and Impedance Analyzer board for Analog Discovery
