Are you looking for what type of hardware you will need, or do you have hardware and are looking for code that will do the acquisition? If you need hardware, you said that you need to sample at very high frequencies. How high? National Instruments have many boards to choose from. You can go as low as 100 ksamples/sec up to around 10 Msamples/second. If you are looking for some code, there are a few good shipping examples that will do analog acquisition. If you select Help >> Find examples (this is for LabVIEW 6.1) >> Hardware Input and Output >> DAQ >> Analog Input >> General - there are around 20 VIs with varying applications that will help in developing an analog acquisition.
