One thing I've found today whilst testing (3 axis vibration sensor this time) is that the 'Signal Options' box is not present, how can I access this?

Hi demodan,

The signal options has been made part of the Advanced Features, and as such is not enabled by default, at least not at the moment...

To gain access to this setting, once within the NVH test software please choose "Options > Advanced Options". Here, choose the Features tab, and check the Enable Advanced Features box.

You will see the Signal Options setting will now have appeared on the Setup tab of the NVH test page.

This is the file requested by Steve Smith

In the rpm/time graph it can be seen that the rpm peaks at 10 seconds, whereas on the 3D frequency graph the order curves (1st & 2nd order) can be seen to peak at about 9 seconds then decay from 9-10 seconds. This is where I think there is a phasing issue.

Hello Demodan and sorry for my late reply.

Thank you for the attached file and the clarification.

I need to dig deeper here with the development team as I am not sure about a number of issues when plotting RPM change in 3D Frequency view.

I need to clarify if RPM data is subjected to a "Transfer" process as with signal data via the accelerometer. (This could account for delay if applicable)

I need to understand the update speed of RPM change in 3D frequency view. (Especially given the abrupt RPM change at 10 seconds in the signal history.)

The accuracy of the time axis in relation to plotting RPM change is challenging too (without rulers) where RPM changes rapidly.

We could have a number of outcomes here, a Bug, New Feature Request, or Characteristic Operation

Rest assured I will catch up with the team this week and feedback.

Thank you again for your patience, take care.......Steve

Hello again Demodan and sorry once again for a late reply.

I have spoken to the development team and the best way to research this concern is to fully look through the build of the software and record how the data is processed in this view with regards to engine speed/frequency

For this I will file a bug reported based on the example and file you have given.

This will go through the resolution process and as soon as I have more feedback I will get back to you.

Thank you once again for your input to date

Take care.......Steve
