Please send some screen shots describing your noise. Else we can not help you

Besides which, my opinion is that Express VIs Carthage must be destroyed deleted

Hi,

 

I am generating sine signal of 0.2 V and Frequency 1 Hz in PCI Card 4461.After examining the signal in Tecktronics TDS 340 CRO the sine wave is not clear and i can see spikes and disturbances at the peak of the Sine wave.Clean sine wave is not visible

 

Regards,

Sneha
