Signametrics 122
Parameter Type/Description
nDmm
int Identifies the DMM. DMMs are numbered starting with zero.
iPol
int 0 indicates to the DMM to measure the negative part of the signal,
1 indicates the positive width.
lpdNwid
double * Points to the location which holds the negative width.
Return Value The return value is one of the following constants.
Value
Meaning
DMM_OKAY
Operation successfully completed.
Negative Value
Error code
Example double w; int state; state = DMMReadWidth(0, 1, &w);
DMMReady

Description Return the ready state of the DMM following trigger operation.
#include "SMU2060.h"
int DMMReady(int nDmm)
Remarks Following the completion of a triggered measurement event, be it hardware or software,
the DMMReady function is used to detect completion. The DMMReady function
checks the DMM and returns TRUE (1) if ready, and FALSE (0) otherwise. Once a
TRUE status is returned, the DMMReady function should not be used again since the
DMMReady function clears some flags in preparation for data transfer when it detects a
ready state. See DMMArmAnalogTrigger, DMMArmTrigger, DMMTrigger, and
DMMReadBuffer for more details on this function.

Return Value The return value is one of the following constants.
Value
Meaning
TRUE
DMM is done and buffer is ready to be read.
FALSE
DMM is not ready.
