Filtering: When, Where, Why and How?


We have an article in the Library section of our website covering Filtering: When, Where, Why and How. The article was written by our very own Steve Smith, and covers the filtering options available to you when using PicoScope.

This ten minute video complements the article, giving visual guidance on how the filters work, and how to set them up. To watch the Filtering: When, Where, Why and How? video, please view it on YouTube.

If you want to read the Filtering: When, Where, Why and How? article, please find it within the library section of our website.

PicoDiagnostics: BETA features


Our PicoDiagnostics software currently has a BETA release. One exciting feature in this latest release is a real-time feature when using NVH, to assist in the capture of harshness signals, such as knocks, creaks, and squeaks. While such noise and harshness signals are annoying, they are present for a very short period of time, with insufficient energy to be transferred and displayed in the Frequency Display (FFT) of the NVH user interface.

Those of you who have used the NVH software, may have noticed the effect on the signal history chart, when monitoring vibration and noise, when the vehicle hits a pothole. The event (pothole strike) is captured in the signal history, as this displays the input of the attached microphone or accelerometer live (relative to time). Such events are not transferred for view in the Frequency Display as we require a minimum of 2.5 seconds of continual disturbance in order to process the event. Until now, symptoms such as these would be reserved for listening devices, enabling the technician to listen to the intensity of noises delivered to a headset from microphones placed about the offending area of the vehicle. The results however are subjective and open to misinterpretation...

Steve Smith, Pico Technology's Automotive Technical Specialist covers this update to the beta software in great detail on our support forum. To read on, and find out what the new Time Domain feature could mean for you, please view the New features of beta NVH software thread on the forum.

You can download the beta versions of both PicoDiagnostics and PicoScope Automotive directly from our website at
