Overview

This illustrates how to modify the buffer size to produce the approporiate waveform at low frequencies(< 38.147 Hz) with a PXI-5422 device.

 

Description

This example examines whether the output frequency is lower than the minimum frequency. If so, an expanded buffer is aassigned to the Fgen task.

 

Requirement

Software:
    Labview 2012 (or compatible)
    NI-Fgen driver which is compatible with your hardware and version of LabVIEW
Hardware:
    PXI-5422 device

 

Steps to Implement or Execute Code

1. Check the frequency of the desired waveform
2. If < 38.147 increase the buffer size to 5000000
3. Run the VI
