measuring point in the diagram and also modify the position of the sidebands.
The cursor information above the diagram displays the measured values for
the base cursor as well as the differential delta of the sideband frequencies.
The measured values of the harmonics are each displayed as vertical text next
to the corresponding vertical line.
Revolutions cursor
The
revolutions cursor
marks the frequency that is assigned to a
specific speed with a line.
The revolutions value is calculated as follows: Revolutions n [Rpm] =
60 * Frequency f [Hz]
1. Select the

. The revolutions cursor is
displayed differently, depending on the type of diagram (FFT or time signal):
In an FFT diagram, a single revolutions cursor is displayed at the point
previously specified for the speed in the dialogue. The cursor information
above the diagram shows the base cursor value as well as the speed setting.
