Updating rate

[Sara_Marmarchi]

Hi,

I want to do a project and I have some problem with the Updating rate.

we want to simulate a nerve and then read its response to that signal. we are using the USB6003 board but the problem is its Updating rate which is 5KHz. this updating rate is not enough for our reading and will not give us the accurate waveform we want but the problem is that the updating rate of the DAQ board is related to the board hardware so it's not something that I can change. so I thought to use a DAC for the digital-to-analog convertor. do you think it is a good idea? 

I thought of using upsampling but it will not give me the accurate wave anyway.

I found a higher-level DAQ board with a 20KHz updating rate but it's expensive so I'm looking for a way to rig it.

If you feel that NI DAQs are expensive, you can try alternatives such as MCC DAQ and LabJack

Don't skimp on hardware as the measurement performance depends on the hardware.
