Frequency analysis

The InnoScope can control the frequency analyzer InnoAnalyzer for an event triggered analysis.
Frequency analysis

Start the InnoAnalyzer

1. Start the InnoAnalyzer
The connection between InnoScope and InnoAnalyzer (if licensed) is established by clicking the button Switch on frequency analysis or the button Switch on FRF. This copies the data of the InnoScope after a trigger event and calculates and displays the frequency spectrum or the frequency response function.
An InnoAnalyzer window will be placed on the right side of the InnoScope. The InnoAnalyzer is controlled by the InnoScope and will analyze the shown time range.
There are the following dependencies:
  • The InnoScope starts the InnoAnalyzer.
  • The InnoAnalyzer stops if the InnoScope is stopped.
  • The InnoAnalyzer is moved together with the InnoScope window.
  • The analysis in the InnoAnalyzer is triggered by the InnoScope.
  • If the InnoScope is waiting for a trigger no analysis is performed.
  • If the InnoScope is closed the InnoAnalyzer also closes.
  • Changing the signal source in the InnoScope changes also the signal source in the InnoAnalyzer provided that the InnoAnalyzer is licensed for this channel.
  • Changing the measurand in the InnoScope changes the measurand in the InnoAnalyzer. The units can be set independently.
  • Changing the band filter in the InnoScope sets the maximum frequency in the InnoAnalyzer.
  • The settings for pre and post trigger in the InnoScope determine the time interval for analysis. Since an FFT only allows discrete time windows at a certain sample rate it may occur that the InnoAnalyzer will fill missing values with zeros.
  • Conflicts caused by certain InnoAnalyzer settings are marked yellow.
