Thanks for nice explanation. I just can't find any video's describing frequency response analysis (output/input). I would assume that Crosspower PSD/Crosspowers Power and FRF options of Channel Processing are related to that? It would be great if Simcenter will come up with videos describing this functionality.
@@SimcenterTesting Thank you for your prompt reply but this link doesn't seem to work. Is it about FRF in general or about its implementation in Simcenter? The latter is what I'd like to learn about.
An autopower is based on the fourier transform, but it is squared to remove phase: community.sw.siemens.com/s/article/the-autopower-function-demystified. Both a Fourier Transform and a Autopower are typically calculated based on a single signal. A cross power is frequency function calculated between two separate signals.
Throughput is the time waveform recorded directly from the transducer. It can go above and below zero. Overall level is a sliding rms calculation performed over a small frame of the throughput. More info: community.sw.siemens.com/s/article/root-mean-square-rms-and-overall-level

This article has some FRF description: community.sw.siemens.com/s/article/what-is-a-frequency-response-function-frf

Are Auto power spectrum and cross power spectrum types of Fourier transform representation

Many thanks for this video. What's the name of this software and how can I have access to it?

What is the difference between throughput and overall vibration in simcenter test lab? Is there a relation between them?
Throughput is the time waveform recorded directly from the transducer. It can go above and below zero. Overall level is a sliding rms calculation performed over a small frame of the throughput. More info: community.sw.siemens.com/s/article/root-mean-square-rms-and-overall-level
Thank you so much guys. I what know how to do SRS and differentiation and integration of a signal

Thanks, Very well explained. Can you please guide me to PSD?
