em noise?

[Geophysics]

Hi,

I am suing pci-4661 and the 'getting started with sine' vi. when I make the magnitude / phase measurements on my test resistor / capacitor network the error above 100Hz is ~ 300 rads! below 100Hz, especially below 10, it is really accurate. I have all the settings to default. any idea what causes the error? any way to fix it?

cheers,

Dimitris

Hello Dimitris,

I would like more information on your application and the error you receive with your PCI-4461.  Please post your code and how I can reproduce the error.  Please explain the results you expect to achieve.

Hi Ima,

I think I had a wiring error (on my circuit board) - now the system appears to work fine - if I anticipate any problems in the near future I will post them.

Thank you for the response.

Cheers,

Dimitris

Hi Dimitris,

I am glad to hear that everything is working well.  Please feel free to post if you ever experience unexpected behavior from National Instruments hardware.
