ordertrack: is bandwidth not only in Hz but also in order width settable?

Hello,

I want to do engine order analyses with ordertrack. For that purpose the bandwidth around the order which is used for analyses is crucial.

In matlab help (https://de.mathworks.com/help/signal/ref/ordertrack.html#bvaw5ra-1-rpmrefidx) I find only the bandwidth parameter which uses a fixed bandwidth in Hz like this: https://community.sw.siemens.com/servlet/rtaImage?eid=ka64O000000kDIW&feoid=00N4O000006Yxpf&refid=0EM4O00000113fd

What I am looking for is bandwidth in "order mode" that means at lower rpm the bandwidth around the order is smaller and at higher rpm the bandwidth is higher like this:

Is this possible with matlab ordertrack function?

Hi,

I understand that you want to use varying bandwidth (“order mode”) using ordertrack. However, this functionality is yet not present in the ordertrack function.

I hope this answers your question.
