Burst IO mode for USB-2020

[Yiou Zhang]

I have a USB-2020 board and would like to make full use of its 20 MS/s sample rate. Is it possible to set the burst mode in either Labview or Matlab? Is there any documentation for this?

Hello @Yiou Zhang.

The 'Data Acquisition Toolbox Support Package for Measurement Computing Hardware' was developed by MathWorks.  MATLAB's documentation does not reference BurstIO support for the USB-2020.  To determine if BurstIO is supported, set your example to acquire a finite number of samples and increase the sampling rate after each run, until it appears to fail.

Next, though it's not documented in the ULx for NI LabVIEW Help, BurstIO is automatically enabled as soon as the user sets the USB-2020 to acquire a finite number of samples (up to 64 MS to the onboard memory), at a rate > 8 MHz.  

The other software option is to use the Universal Library with a supported IDE.

Here is a link to a MCC Knowledgebase article featuring the USB-2020 with sample code in C#:  https://kb.mccdaq.com/KnowledgebaseArticle50586.aspx 
Lastly, the BurstIO mode was not implemented in MCC's other software applications, DAQami and TracerDAQ, nor in DASYLab.
