The Differentiate operation allows you to calculate the differential of a waveform. You are first prompted for the number of the waveform to differentiate. You are then asked for the number of the new waveform, which must be different from the first one. If the second waveform already exists, it is erased. The differential is then calculated, and placed in this second waveform.
The resulting waveform contains differences between adjacent sample points in the first waveform, with the first point set to zero. An alternate unit specifier is set up at the end of the channel name for the new waveform, to indicate the units in which the waveform will be scaled when displayed.
