Go to Sample Function
Analysing signals with SIGVIEW often includes zooming in to a smaller part of the signal and moving that part through the whole signal to observe changes in the time or frequency domains. For better navigation in a longer signal, SIGVIEW includes the "Go to sample" function which enables you to position your currently visible part of the signal to an exact absolute position in the whole signal. Please note that this function requires the selection of a smaller part of the signal - it will not zoom-in or change the length of a visible signal part in any way.
You can start this function from the main menu, “Play & Navigate/Go to sample...” option. The following dialogue will appear:
You can define signal position in signal units (for example seconds, Hz, etc.) or in a number of samples/values. These two values are mutually dependant and both will be synchronized by SIGVIEW each time you change one of them.
You can also choose if the value entered in the above two fields should be used to define the leftmost or center value of the visible signal part.
This function can also be used from the Control Window to set multiple signals to the same position, i.e. synchronize them prior to starting some analysis operation on multiple signals. To use this feature, simply select one or more signals in the Control Window and select the "Go to sample..." function from the context (right-click) menu. SIGVIEW will use the sample rate of the first selected signal to convert signal units to samples in the dialog, but will position each signal to its correct position in signal units.
If the requested position is invalid for the actual signal, for example 5.2 seconds for a 5 second long signal, SIGVIEW will try to move signal part as much as possible in the requested direction, i.e. will move to the end of the signal in this case.
