Can LabView replace a waveform generator in an equivalent time sampling application?

Go to solution

Hello all!

I am trying to get together a list of equipment that I need for implementing an equivalent time sampling application. A similar project used an Agilent 33220A to generate a waveform, but I was wondering if LabView could be used in lieu of that equipment?

Thanks in advance!

Maybe. You could use the sound card to output a signal in the audio bandwidth, but you will be limited by the max amplitude you can provide with respect to a function generator, in addition to any voltage offsets you may want to add to the signal. You could use a DAQ device to output your waveform but you need to look at the specs to see if it matches your needed frequency and output levels.

Thank you for the quick response! I was looking into using a DAQpad 6016 or maybe a FPGA. I am still in the beginning stage of my project, so I am just trying to get some ideas.

There are numerous applications where the FPGA cards are used to create multiple waveforms and frequencies.

Unless there is a misprint or I am looking at the wrong information a DAQpad can only output 300Sa/s, which is pretty low. A fpga can work, but it more expensive and difficult to program. I would recommend looking at low cost DAQ devices.

Thank you so much for your help! I will look into other daq possibilities!
