| Term | Main definition |
|---|---|
| sample rate | Defines the number of acquisitions (i.e. measurements) per second. Specified normally in MS/s (megasamples per second = 1,000,000 measurements per second). |
| sampling rate | Frequency at which analog signals are converted by the analog-to-digital converter of the input channel into digital data. The sample rate should be at least twice the highest freequency in the signal to be acquired (Nyquist). |
| sensitivity | The smallest quantity that can be measured and displayed. |
| SENT | SENT (Single Edge Nibble Transmission) - a serial transport protocol used for communication between sensors and a controller in automotive applications. |
| settling time | Time required for an analog output to reach its final value. |
| SFDR | Spurious free dynamic Range - Ration of the rms value of the signal to the rms value of the worst spurious signal. This specification represents the smallest value of a signal that can be distinguished form a large interfering signal. |
| SINAD | Signal to Noise and Distortion Ration - Ratio of the rms signal amplitude to the mean value of the root-sum-square of all other spectral components. |
| single shot | A single shot acquisition is need if the signal to be measured did occur only once or very rarely. |
| slew rate | Maximum rate of change of output voltage per time (expressed as volt per second). |
| spurious free dynamic range | Ration of the rms value of the signal to the rms value of the worst spurious signal. This specification represents the smallest value of a signal that can be distinguished form a large interfering signal. |
| synchronization | Time coordination of multiple instruments or functions with in a system. |
