Signal Types

Signal Classification

Nexus classifies all imported data into signal types based on their dimensionality and whether they have timestamps:

Type	Suffix	Description	Example
0D	-	Single scalar value	A single temperature reading
0Dts	Time series	Scalar values over time	Temperature ramp, voltage log
1D	-	Single spectrum/line	An energy spectrum
1Dts	Time series	Spectra over time	EELS spectrum series
2D	-	Single image	A micrograph
2Dts	Time series	Images over time	In-situ TEM video

The ts suffix indicates the signal contains a time dimension - these signals can be played back on the timeline and correlated with other time-series data.

How Signal Type Affects Visualization

Each signal type is automatically matched to the appropriate viewer:

Signal Type	Default Panel	Alternative Panels
0Dts	Time Series Graph	Scatter (XY Graph)
1Dts	Spectrogram	-
2Dts	Image Viewer	-
2D	Image Viewer	-
1D	Spectrum Plot	-

When you drag a signal onto the canvas, Nexus creates the matching panel type automatically. See Panels for details on panel creation and layout.
