If AC is selected, the frequency offset is automatically corrected, i.e. the trace is
always symmetric with respect to the zero line.
●
PM time evaluation
If DC is selected, the phase runs according to the existing frequency offset. In addi-
tion, the DC signal contains a phase offset of ± π.
If AC is selected, the frequency offset and phase offset are automatically corrected,
i.e. the trace is always symmetric with respect to the zero line.
