Dear Aspired
SCXI is great for this sort of biomedical application as there are isolated amplifiers available. We've used the SCXI 1120 isolated amplifier for this purpose. Note this is not suitable for human use. email me and I can send you info on the issues regarding human use. The issue with 12 lead is that some of the leads are referenced together in a very specific way. Lead1=VLA-VRA Lead2=VLL-VRA Lead3=VLL-VLA you can connect these as differential inputs. However the referencing of the amplifier has to be considered. The precordial leads are referenced to what is called the Wilson Central Terminal. Some circuitry is required outside the Amplifier system to set this up. For human use we've done projects interfacing 3rd party 12 lead systems to LabVIEW. This was done through an ActiveX control we developed. If you need references or assistance feel free to contact me at [EMAIL PROTECTED] or via www.madry.com.au cheers Andrew Madry
