6.9.7 Collect a Filtered Orbit
Filtered Orbit lets you analyze the phase relationship between two or four channels at a
specific order of turning speed. Orbit plots show the relative movement of a rotating shaft
with respect to some reference point.
Note
Filtered Orbit is only available for the two and four channel analyzer. For orbit plots, the analyzer uses
the lowest input channel for the X axis and the next input for the Y axis. For a two-channel orbit using
inputs A and C, A =X and C= Y. If you use inputs B and D, B=X and D=Y. For a four-channel dual orbit,
A=X1, B=Y1, C=X2, and D=Y2. A and B are used for the first orbit, and C and D are used for the second
orbit.
You can create orbit plots using normal two-channel or four-channel route data, but you
must set up the acquisition to collect the correct amount of data. Also, filtering is not
included. Filtered Orbit eliminates the complicated setup. Filtering the data lets you arrange
the orbit’s parameters so only certain frequencies are included in the orbit plot, and the
pattern is easier to recognize.
Prerequisites
Ensure all sensor inputs use the same data units.
