DMMOutputSync
SMU2060  SMU2064 
Description Generate as Sync output pulse or level.
#include "SMU2060.h"
int DMMOutputSync(int nDmm int iMode, double dWide )
Remarks This function has three modes. It sets the Sync output line low (iMode=0), it can set it
high (iMode=1) or generate a pulse of dWide in width (iMode = 2). In modes 0 and 1 the
value of dWide is ignored. If iMode = 2 the polarity of the Sync pulse is determined by
its previously setting by the DMMSetSync() function. The pulse width (dWide) can be
set from 100us to 1.04s. In all three modes the Sync pulse gets set regardless if it was
enabled by DMMSetSync(). The sync can also be activated to synchronize
