C HAPTER T WO Overview
HorizontalUnits
Applies to: Digital, Histogram, Persist, Waveform, XY
Description: Resolution of the readout of horizontal values. Not directly related to the sample period.
Example:
Dim HorizontalUnits As String
HorizontalUnits = app.Acquisition.C1.Out.Result.HorizontalUnits
HorizontalVarianceArray
Applies to: Waveform, XY
Description: Variant array with the variances from the nominal sample times. Used on WaveExpert oscilloscopes
Example:
Dim HorizontalUnits As Double
HorizontalUnits = app.Acquisition.C1.Out.Result.HorizontalUnits
HorizontalVariances
Applies to: Waveform, XY
Description: Number of elements in HorizontalVarianceArray
Example:
Dim HorizontalVarianceArray
HorizontalVarianceArray =
app.Acquisition.C1.Out.Result.HorizontalVarianceArray
IndexOfFirstSampleInFrame
Applies to: Waveform
Description: Index of the first sample that appears in the graticule. This is typically index 1, since index 0 is off-
grid to the left. When traces are zoomed
Example:
Dim IndexOfFirstSampleInFrame as Long
IndexOfFirstSampleInFrame =
app.Acquisition.C1.Out.Result.IndexOfFirstSampleInFrame
LastEventTime
Applies to: All Result interfaces.
Description:
Time of the last contributing event in a set. Useful only when the result includes data produced by a sequence
acquisition, or a cumulative operation such as averaging. Times are returned encoded as a currency value
(VT_CY) within a variant; see description for FirstEventTime for decoding details.
Example:
Dim LastEventTime
Dim TimeString as String
LastEventTime = app.Acquisition.C1.Out.Result.FirstEventTime
TimeString = DecodeTimeProperty(LastEventTime)
See FirstEventTime for the code for the function DecodeTimeProperty, which is the example of decoding
LastEventTime.
