Sir,
I can do your project. In your project you want to acquire Digital waveform signal using NI USB-6009 DAQ card and use this signal to stimulate four electrode.
I also have done similar activity in my project there I use different signal generator to generate different signal like frequency , amplitude and PWM and acquire signal using PXI-6259 M-series DAQ .
I have developed Testbed facility for marine ship M-15 Gas turbine using NI labVIEW and Hardware. Testbed facility includes:
1. Operator warning system
2. Data acquisition and monitoring system.
3. Engine control system.
I have used various NI software (8.6, 2009, 2010 & 2011) and hardware like PXI-1058, PXIe-1078, cRIO-9073, SCXI module and DAQ module( PXI-6259, PXI 6229, USB 6009).
So, I think I am the best freelancer for this project.
Thanks,
Srikant Kumar
