ni pci 6259 tutorial

[Naser1363]

Hello,

Would you please tell me do existence a tutorial or video for using of NI-PCI 6259?

Thank you for your attention and time.

If you want to do anything specific then mention here. We might guide you.

Thank you for your kind reply.

Would you please tell me maximum frequency that I can generate with Analog Output of PCI -6259.

And would you please tell me maximum frequency that I can measure with Analog Input of PCI-6259.

Have you bothered to look at the main product page?

[Naser1363]

I see this page.
I know it has a 1MS/s Analog input.

But Nyquest theory told we can measure to 500KHz but I don't know in experimental do it decrease or no?

Thanks

[Dennis_Knutson]

Yes, you can measure a frequency of 500 kHz since that meets the Nyquist criteria.

What other 'experimentals' are you talking about? If you are at all familiar with Nyquist, then you should know some of the limitations. For example, you cannot recreate the waveform and perform other measurements accurately. Depends on the input waveform type and what you want to measure. 

Instead of all of these questions about the 6259, you should perhaps start with some of the data acquisition basics such as this though I would have thought you purchased the 6259 with some of this in mind.

[Naser1363]

Thank you.

But in experimental I heard that Nyquist theory does not work.

I heard in experimental (Sample rate must be>4 or 5*Maximum frequency).

So I think I can measure a sine wave with maximum frequency of 200 KHz with PCI-6259.

[Dennis_Knutson]

You really need to define 'experimental' and what you are trying to measure. As I said, if all that you want to measure is the frequency, then Nyquist applies.

This is the second time I asked you define what you want to measure. Is that such a hard question to answer?

[Naser1363]

I want to measurer impedance of a device.
I use a resistor in input of device and I generate a sine voltage with
Analog output of PCI 6259.
Then I measure voltage of resistance and I can measure current of circuit.
Then I divide voltage of device to output current and impedance calculate.
My interested frequency is (10 KHz-500 KHz)
 I want to know do Analog output of PCI 6259 can generate a sin wave
with frequency 500KHz and do Analog Input of PCI 6259 can measure a
sin wave with frequency 500KHz?
