I have USB NI 6009  device which I use in my experiment.I have a Analogue siganal from a Photomultiplier tube.I need to convert that to a digital

signal and need to be saved that signal into a file.saving to a file thing is ok to me.But I do not know how to convert that signal to digital and get that signal in through the USB 6009 usb device ...please let me know this as soon as possible.thank you very much.I am in a hurry to do this

Posting the same message twice will not get you an answer any faster.

Use the Analog Input of the USB-6009.  When you Read the input you get a number or a series of numbers, depending on how you set up the acquisition, and those numbers are the digital representation of the signal at the input to the DAQ device.

What programming language and what drivers for the device are you using?

thanks for the reply.I put the same message twice by mistake.sorry about that.I use Labview 2010 and I get the signal from Photomultiplier tube to analog filter and then It should come to the USB 6009 directly and inside that I should be able to collect the analog signal and convert to digital and save it to a file.

That digital signal is one of my data.So it should be saved.thanks

I recommend using the LabVIEW Example Finder (in LabVIEW go to Help->Find Examples...) and search for TDMS Logging - Cont Log and Read Data.  That example should get you to where you want to go.  It will save the data to a TDMS file as you read the data from the DAQ.  You can then use the TDMS Viewer to look at your data.
