C HAPTER T WO Overview
XMaxPossible
Applies to: XY
Description: Maximum possible value of the X coordinate
Example:
Dim XMaxPossible As Double
XMaxPossible = app.Math.XY.Out.Result.XMaxPossible
XMinPossible
Applies to: XY
Description: Minimum possible value of the X coordinate
Example:
Dim XMinPossible As Double
XMinPossible = app.Math.XY.Out.Result.XMinPossible
XOffset
Applies to: XY
Description: Potential difference between ground and the horizontal center of the XY grid. For example, with
VerticalOffset
of the X coordinate’s source trace = +50 mV, the center of the screen represents -50 mV: with an
offset of -21mV, the center represents +21 mV. (I.e. centerline voltage + VerticalOffset = 0)
Example:
Dim XOffset As Double
XOffset = app.Math.XY.Out.Result.XOffset
XPerStep
Applies to: XY
Description: Smallest step size in the numerical values that can be read out from the DataArray utilzing 16 bit
signed integer values. Note that the X range is just about 65536 * XPerStep. (See XMaxPossible and
XMinPossible.
)
Example:
Dim XPerStep As Double
XPerStep = app.Math.XY.Out.Result.XPerStep
XResolution
Applies to: XY
Description: Vertical resolution of the X coordinate, which is the actual smallest difference that can be practically
resolved. Using averaging can improve the resolution by the square root of the number of sweeps in the average.
For example, if 16 averages are set via pre-processor averaging or by using the Average math function, the
resolution is improved by a factor of 4. For 100 sweeps it improves by a factor of 10.
Example:
Dim XResolution As Double
XResolution = app.Math.XY.Out.Result.XResolution
