how to know the integration time of a specific data aquisition?

[josan]

I am using the PCI 6221 board to aquire voltage info from a photodiode. In the Aquire and graph with internal clock VI, what I can do is to define a data aquisition frequency. If I set it at 1KHz, what is the integration time and dwell time of the data aquisition?

Thanks !

josan,

By specifying the frequency of your data acquisition, you generate a hardware-timed signal on your board at 1kHz, which is used as the sample clock of your analog to digital converter. More information on the analog to digital converter in your device can be found here. The integration time of your device is on the order of microseconds, though we do not specify this. Is there a particular reason you need to know this number? It is not often important in board-level specifications.

Thanks, Ryan!

I am just curious about this and thinking of some future use of my set up
