Amplitude (voltage) measurement. The mean over one waveform cycle. For
non-cyclical data, you might prefer to use the Mean measurement.
If StartCycle = EndCycle then return the (interpolated) value at StartCycle.

Timing measurement. The amount of time between the MidRef crossings of two
different traces or two different places on the same trace.
Delay measurements are actually a group of measurements. To get a specific
delay measurement, you must specify the target and reference crossing polarities
and edges.
