Histogram
The Histogram interface is used for all histogram traces. Histograms can be configured on most
oscilloscopes as a math function (Fn). Histograms are also used in various analysis modes, especially on
Serial Data Analyzers, where the HTIE trace is the source data for the algorithm to calculate Total jitter
(Tj). The key property is BinPopulations, which is a 1D array of the bin populations.
Example paths to HTIE Result interfaces:
app.Math.F1.Out.Result
app.SDA.Htie.Out.Result
Note: This example assumes that F1 is set up as a Histogram.
Param
The Parameter interface is used in the Measurement and Pass/Fail systems to hold both individual results
and result arrays. The key properties for the Parameter interface are Value and ValueArray. Value holds
the last measurement or P/F result, while ValueArray holds all measurements taken for the last
acquisition. This is an important distinction to remember depending on the measurement assigned to the
parameter, as the values may or may not be the same. For example: if the source waveform is 1000
cycles of square wave, then the Frequency measurement will have 1000 values in the ValueArray and
Value will be the same as the 1000th (last). Whereas, Min or Max measurements on that same waveform
will only have one value in the ValueArray, and Value will be that same value.
Example paths to Param Result interfaces:
app.Measure.P1.Out.Result
app.Measure.P1.Sdev.Result
app.Measure.Measure("P1").Out.Result
Persist
The Persist interface is most often found when using software options that create eye diagrams or other
waveshapes that are the result of overlaying multiple waveforms. (Note that this does not apply to the
Persistence display mode.) The key property in the Persist interface is the DataArray, which is a 2D array
containing the population of each pixel of the persistance map.
Example paths to Persist Result interfaces:
app.SDA.Eye.Out.Result
app.SDA.Eye2.Out.Result
