How to Choose the Best Portable Digital USB Oscilloscopes

Especially if you are a first-time buyer, it is easy to be overwhelmed. Do not be confused with too many oscilloscopes available. To help you trim the options to include in your shortlist, here are some factors to think about:

  • Type of USB Oscilloscope: You will have two main choices, the first one being a microprocessor-based USB oscilloscope. It has a built-in microprocessor, which is the one responsible for conducting the readings. Data has to pass through several stages, creating a bottleneck. If you want a more accurate option, then it is best to choose an FPGA-based oscilloscope. It processes more information in a given time, which means that the results displayed are more accurate.
  • Bandwidth: A high bandwidth is one of the most crucial considerations, directly linked to better accuracy. The Five Times Rule is critical, which means the chosen device’s bandwidth should be at least five times greater than the signal that will be read. It significantly minimizes the margin of error.
  • Sampling Rate: Another important technical specification is the conversion of input signals to discrete values. It is best to choose a device with a large frame rate, which means that the readings will be more accurate. You should also look at the minimum sample rate.
  • Memory Capacity: This is reflective of the sample readings that the USB device can store. The higher the memory rate, the more sampling rate you will capture for the reading. This is especially important for professionals.
  • Probes: These are the ones responsible for taking the measurements from the source. Their quality directly impacts the results. From synchronization to the grade, see to it that the probes will help in yielding accurate results.
  • Software: USB oscilloscopes can come with pre-packaged software. Read reviews from the other users and learn from their insights. Choose user-friendly software so that using the device will not be frustrating. Look at the software’s functionalities so that you can make the most out of the device.
