Description Enables and sets polarity of Sync output line.
#include "SMU2060.h"
int DMMSetSync(int nDmm, int bEnable, int iPolarity)
Remarks This function enables or disables the Sync output (available at the DIN7). To enable it,
set bEnable TRUE (1), or FALSE (0) to disable. iPolarity effects the sync output level.
iPolarity set to 0 causes low going pulse, and 1 sets to high or positive pulse. This signal
can be used as a busy signal or to synchronize the DMM to other instruments. The
default is a disabled output, and active low. When enabled, all measurement funcitons
generate a pulse corresponding to their measurement cycle.
