USB-6008 and CVI 8.0

[Srm27]

Hi,

I have a USB-6008 which I need to control with CVI 8.0.

Where do I start?

I have a square wave form of 1V at 2KHz which I need to measure and it would be good to use USB-6008.

Can any help or suggest as to how I can cheaply and reliable do such a measurement using CVI?

We also use ADAM modules to do a straight DC voltage measurements and relaying switching.

Thanks for the help

Hi,

the best place to start is with the shipping examples. I'm assuming that you've got the USB-6008 recognised as a DAQmx device in Measurement and Automation explorer already by installing DAQmx (available for download here https://www.ni.com/en/support/downloads/drivers/download.ni-daq-mx.html) and then plugging in the USB-6008.

Have a look under the help menu item in CVI 8.0 for the example finder (so help>>find examples)
and then go to the hardware input and output and then the daqmx section.

There you'll find lots of example code that will use your 6008 in various ways, so really it depends on what you want to do with the analysis of the signal. (You can also limit the example finder to particular hardware setups on the bottom left corner - select your usb-6008, or add it to the list, and then select the "limit results to hardware" tick box. That way you know the examples you're looking at are compatible with this.

Do you need to know frequency content (so counter measurments), voltage (amplitude) (so analog measurements) etc.

Hope that helps.
