DMMWaitForTrigger
SMU2060  SMU2064 
Description
Put the DMM in a wait state which gets relesed on trigger event.
#include "SMU2060.h"
int DMMWaitForTrigger ( int
nDmm
)
Remarks
Setup the DMM for external hardware trigger (Trigger input DIN7 connector).
Following reception of this command the DMM enters a wait state. It waits until the
selected trigger edge, previously defined by
DMMSetTrigPolarity() i s detected. During
the wait, no other command except for DMMReady() or DMMDisarmTrigger() should
be issued. Prior to issuing this command the DMM may be set up for a composit
function such as Capacitance or any other measurement mode. Monitor readyness using
the
DMMReady() command. While no trigger is received, it will return a FALSE (0). If
trigger event occured it will returne a TRUE (1). It is possible to terminate the wait for
trigger by issuing
DMMDisarmTrigger() command. Also see DMMArmTrigger() ,
DMMDisarmTrigger() and DMMSetTrigPolarity() .
Positive Edge is imlied by a transition from 0V to a voltage over 3.5V at the Trigger
input line. Negative edge is implied by transition from a voltage over 3.5V to 0V.
Parameter Type/Description
nDmm
int Identifies the DMM.
Return Value
The return value is one of the following constants.
Value Meaning
Negative Value
Error code
DMM_OKAY Normal response
Postive Value Warning code
Example
int status = DMMWaitForTrigger(0);
DMMWidthStr
SMU2060  SMU2064 
Description
Return the indicated pulse width in string format.
#include "SMU2060.h"
int DMMWidthStr ( int
nDmm,
int
iPol,
LPSTR
lpszNeg
)
Remarks
This function is the string equivalent of DMMReadWidth . The measurement results are
stored at the location pointed to by
lpszWidth
. See DMMReadWidth for more details.
Parameter Type/Description
nDmm
int Identifies the DMM. DMMs are numbered starting with zero.
