Phase comparison signals are important for the analysis of 87PC operation. As such, they are recorded in oscillography. A
list of the 87PC channels recorded in oscillography is shown as follows.
Table 5-26: 87PC oscillography channels
See the Application of Settings chapter for calculation examples for the phase comparison elements.
