7.3.2Creatingthetransferfunction
The oscilloscope automatically records the amount and phase response of the 
controller according to the controller settings. This produces an initial estimate of the 
control quality. To determine the transfer function, the noise amplitude (motor rated 
current) and the sampling time (default: 0.125ms) must be specified. Click the "Start 
Test Signal" button.
