1-Port Phase: Press this submenu key to set the phase of a
reflection measurement. 1-Port phase displays the phase of
the reflection measurement of the device that is connected to
Port 1. The data are displayed from –180° to +180° because
the measurement cannot tell the difference between one
cycle and the next. This display method removes the
discontinuity from the important 0 degrees area that is used
as the phase reference.
The 1-port phase measurement is most useful when making
relative measurements (comparing the phase of one device
to the phase of another) by utilizing the Trace Math function
(Trace – Memory).
