GxDmmGetAperture

Purpose

Returns the capture aperture in terms of line cycles

Syntax

GxDmmGetAperture (nHandle, pdAperture , pnStatus)

Parameters

Comments

The aperture is expressed in terms of Line Cycles as set by the GxDmmSetLineFrequency function. The Aperture can be a fraction of a line cycle. For example, the aperture can be set to 0.1 Line Cycles which would represent approximately 0.00167 seconds if the Line Frequency was set to 60Hz.

Example

The following example gets the aperture:

SHORT nHandle, nStatus;

DOUBLE dAperture;

GxDmmGetAperture (nHandle, &dAperture, &nStatus);
