Lin. phase-frequency response measurement

The program Lin. phase-frequency response measurement is used for phase-frequency response evaluation. The program is a SCADA-project which is delivered together with  ZET 017-U vibration controller.

Programs for FR measurements are included into ZETLAB VIBRO Software set which is delivered together with ZET 017-U vibration controller

VCS controllers are used for measurements purposes. Integrated generator produces the testing signal. The testing signals are connected to the inputs. The program Lin. phase-frequency response measurement enables measurements performance by 8 channels simultaneously.

Generator output produces testing voltage with linear change of frequency value within the frequency range set by the operator. Phase difference measurements are performed in relation to the selected reference channel. In the course of frequency response measurements the following parameters are depicted: current frequency, generator signal oscillation diagram, remaining measurements time and phase-frequency respose diagram. The results can be represented in radians and degrees (in the course of absolute measurements) or in dB (in the case of relative measurements).

Phase-frequency response diagram is saved to a file for further representation (in graphical or digital format) and printing.

For program operation one have to install  SCADA ZETVIEW software.
