  • What you really need to know about sample rate
    By and large, discussions of sample rate are like watching paint dry. Do we really have to get into the details? After all, everyone knows that you only need to sample at twice the frequency of your signal of interest to get good results, right? If you answered “right!” to that last statement, perhaps you should read on.

  • Using USB for test and measurement: benefits and potential dangers
    Recognised for its ease of use and flexibility, USB is one of the fastest growing buses within the computer and electronics industries today.
  • Five tips to reduce measurement noise
    Ensuring measurement accuracy often means going beyond reading raw specifications in a data sheet. Understanding an application in the context of its electrical environment is also important for securing success, particularly in a noisy or industrial setting. Ground loops, high common-mode voltages and electromagnetic radiation are all prevalent examples of noise that can adversely affect a signal.
