Using PXI-4139 to create a multisine signal?

Hello everyone,

 

This is my first time using NI products. 

 

I have a PXIe-4139 SMU, and I would like to use this card to output an arbitrary waveform, specifically a multisine signal. I have read that the 4139 is primarily intended for DC measurements and low-frequency AC measurements, so it is not optimal for generating complex multisine waveforms. 

 

I am thinking of using LabVIEW as the programming environment. I have looked into the "Arbitrary Wave" function and would like to use it to create individual sine waves with different frequencies, phases, and amplitudes. I would then sum the individual sine waves to create the multisine waveform. 

 

I plan to use DAQmx to output the multisine waveform to my 4139 card. 

 

Is this possible and would using LabVIEW as the programming environment be the best choice? Is there anything I should be wary of?


Thank you

No, DAQmx is the driver for DAQ devices and 4139 is an SMU and uses NI DC Power driver, no mix matc (like trying to use a key for Audi car in a Volvo truck)

 

You can attempt to generate an arbitrary waveform but SMUs being slow, the generated waveform may not look exactly like what you intended to generate.

 

Why are you trying to generate a multi-sine signal on a power supply?
