6541 data acquisition to feed to an FFT

[PCTEL Rick]

How do I use Signal Express to instantiate my PCI-6541HSDAQ data acquisition card to get it to take samples I can pass to a fft? Does anyone have a sample .vi?

1) Drop the HSDIO Acquisition Block into an empty SignalExpress project
     a) Select the NI-6541 device
     b) Configure the channels to use for the acquisiton
     c) Configure the sample rate
     d) You may need to use a trigger of some sort to start the acquisition, unless you don't care at what point you want to sample data

2) Drop the Digital to Analog block into your SignalExpress project
     a) Pass the acquired digital waveform to this step
     b) Configure the A to D step appropriatly

3) Drop the FFT block into your SignalExpress project
     a) Pass the analog waveform from step 2 to this block

4) Hit the Play button to execute your SignalExpress project and view the results of the FFT
