Cycle mean. 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.
Details of the integration algorithm are given later. Integration Algorithm
Cycle RMS. The true Root Mean Square voltage over one cycle.
If StartCycle = EndCycle then CycleRMS = Waveform[Start].
Otherwise,
Details of the integration algorithm are given later. Integration Algorithm
Delay. Timing measurement. The amount of time between the MidRef and Mid2Ref 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 the reference search direction.
Delay = the time from one MidRef crossing on the source waveform to the Mid2Ref crossing on the second waveform.
Delay is not available in the Snapshot display.
Extinction ratio. Optical measurement between 1 and 100. In real circuits, the extinction ratio is typically 8 to 30. Values ≤ 1 or
≥ 100 generate errors. An Extinction Ratio of 1 or 100 means a problem exists. The optical probe and the instrument must be
calibrated. All inputs are micro watts and are not negative. Extinction ratio is dimensionless.
Extinction Ratio = (High/Low)
Low ≥ 1 μW
Extinction %. Optical measurement.
Extinction % = 100.0 / Extinction Ratio
