Using LabView to control the USB2020 to acquire data at 20MS/s/ch

[gkhuangke]

Hello all

Did anyone work with USB2020 DAQ (form Measurement Computing Corporation)?

I want to know what software can be used to control USB2020 with sampling rate at 20MS/s/ch and then log data to local file afterwards?

Can LabView do that?

Thanks!

Ke

Hello Ke,

The USB-2020 is fully capable of acquire data at 20 MHz in LabVIEW using ULx for NI LabVIEW.  You need to nothing special to enable BURSTIO other than in the ULx Timing.vi set the samples per channel above 8 MHz, and set the sample mode to 'FiniteSamples'. 

Note that the USB-2020 cannot run in continuous mode when BURSTIO mode is enabled.

 

The ULx example: ULx Acq&Graph Voltage-Int Clk.vi is the correct example to use here.

Measurement Computing's Support Engineers can help you with getting the USB-2020 to operate and acquire data in a supported software such as LabVIEW, however what you do with the data once it is acquired is up to you to implement. To write the data to file, I recommend you look at the Express VI, Write To Measurement File.vi
