YPerStep
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 Y range is just about 65536 * YPerStep. (See YMaxPossible and
YMinPossible.
)
Example:
Dim YPerStep As Double
YPerStep = app.Math.XY.Out.Result.YPerStep
YResolution
Applies to: XY
Description: Vertical resolution of the Y 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 YResolution As Double
YResolution = app.Math.XY.Out.Result.YResolution
YUnits
Applies to: XY
Description: Units of the Y coordinate. Typically V for Volts, unless a current probe is in use or if the Rescale
function is being used to change the trace’s units.
Example:
Dim YUnits As String
YUnits = app.Math.XY.Out.Result.YUnits
