4.4.9.2 Signal analysis overview
The ServoSignalAnalyzer offers three basic methods of analyzing systems:
 Analysis in the time range by measuring the step response
 Spectral analysis of individual signals
 Measurement of frequency response (Bode diagram) of the position control or of
individual parts of the control as well as of the control path
These functions are available in the Compax3 ServoManager after the activation
(see on page 251) with the aid of a system-dependent key.
You do not require expensive and complex measurement equipment -> a
Compax3 device and a PC will do!

Systems / signals
Depending on the kind of measurement, the SignalAnalyzer can help analyze the
most different signals and systems.
Signal generator
This allows to inject different excitation signals (step, sine and noise signals) into
the control loop.
Superposed system
For different analyses, superposed systems must be manipulated in order to allow
a measurement. After the measurement, the changes made for this purpose are
reset
C3 software oscilloscope
With the aid of the software oscilloscope, the contents of different objects can be
registered and be loaded into the PC for further analysis.
Control and signal processing
The control of the entire measurement as well as the processing of the uploaded
sample data are made in the PC.
