Optimizing Measurement Accuracy: SPC and Probe Cal
The TDS Oscilloscope provides three features that optimize measurement
accuracy. Signal Path Compensation (SPC) lets you compensate the internal
signal path used to acquire the waveforms and measure based on the ambient
temperature. Channel/Probe Deskew lets you compensate for the fact that signals
may come in from cables of different length. Probe Cal lets you compensate the
entire signal path, from probe tip to digitized signal, to improve the gain and
offset accuracy of the probe. This section tells you how to use both features.
