Identifying noisy bearing in loud environment with oscilloscope ?

Hi Forum. I have a noisy environment with lots of bearings in which there is at least one bearing that is making excessive noise. I remember using stethoscopes for such things in the past, but I have a 4444 and as NVH accessory is automotive only (???) I wonder what would be a simple alternative ? I'm thinking a thin-film piezo on a wand, but I don't really know and figure some people here have this knowledge.

Thank you.

The Automotive NVH solution uses microphones and three axis accelerometers, with specialist software that takes inputs for engine and road speed to perform NVH analysis.

You can use the Test and Measurement version of the Three Axis Accelerometer with our T&M scopes, or suitable microphones, but would need to analyse the data yourself.

Please email support@picotech.com and one of the team will be able to give further advice on this.
