Frequency Response
Frequency response testing functions are available by clicking the RTM Analysis screen Frequency
Response button. Frequency Response screen functions are illustrated in Figure 160 and described as
follows.
Test Mode
Frequency response testing may be performed in Manual or Auto mode. In Manual mode, a single
frequency can be specified to obtain the corresponding magnitude and phase responses. In Auto mode,
