IviDmm Configure MultiPoint
IviDmmMultiPoint Capability Group [MP]
This VI configures the properties that affect multipoint measurements. These properties are the trigger count, sample count, sample trigger and sample interval.
 |
instrument handle The instrument handle that you obtain from the IviDmm Initialize or IviDmm Initialize With Options VI. |
 |
trigger count (1) Pass the number of triggers you want the DMM to receive before returning to the Idle state. The driver sets the IviDmm Trigger Count [MP] property to this value.
Default Value: 1 |
|
sample count (1) Pass the number of measurements you want the DMM to take each time it receives a trigger. The driver sets the IviDmm Sample Count [MP] property to this value.
Default Value: 1 |
|
sample trigger (Immediate) Pass the type of sample trigger you want to use. The driver sets the IviDmm Sample Trigger [MP] property to this value.
When the DMM takes a measurement and the Sample Count parameter is greater than 1, the DMM does not take the next measurement until the event you specify in the Sample Trigger parameter occurs. Valid Values: IVIDMM_VAL_IMMEDIATE—Immediate IVIDMM_VAL_EXTERNAL—External IVIDMM_VAL_SOFTWARE_TRIG—Software Trigger Function IVIDMM_VAL_INTERVAL—Interval IVIDMM_VAL_TTL0—PXI TRIG0 or VXI TTL0 IVIDMM_VAL_TTL1—PXI TRIG1 or VXI TTL1 IVIDMM_VAL_TTL2—PXI TRIG2 or VXI TTL2 IVIDMM_VAL_TTL3—PXI TRIG3 or VXI TTL3 IVIDMM_VAL_TTL4—PXI TRIG4 or VXI TTL4 IVIDMM_VAL_TTL5—PXI TRIG5 or VXI TTL5 IVIDMM_VAL_TTL6—PXI TRIG6 or VXI TTL6 IVIDMM_VAL_TTL7—PXI TRIG7 or VXI TTL7 IVIDMM_VAL_ECL0—VXI ECL0 IVIDMM_VAL_ECL1—VXI ECL1 IVIDMM_VAL_PXI_STAR—PXI Star IVIDMM_VAL_RTSI_0—RTSI line 0 IVIDMM_VAL_RTSI_1—RTSI line 1 IVIDMM_VAL_RTSI_2—RTSI line 2 IVIDMM_VAL_RTSI_3—RTSI line 3 IVIDMM_VAL_RTSI_4—RTSI line 4 IVIDMM_VAL_RTSI_5—RTSI line 5 IVIDMM_VAL_RTSI_6—RTSI line 6 Default Value: IVIDMM_VAL_IMMEDIATE |

Notes
|
 |
sample interval (0.0 s) Pass the length of time you want the DMM to wait between samples. Express this value in seconds. The driver sets the IviDmm Sample Interval [MP] property to this value.
If the Sample Count parameter is greater than 1 and the Sample Trigger parameter is set to IVIDMM_VAL_INTERVAL, the DMM waits between measurements for the length of time you specify with this parameter. Otherwise, this property does not affect the behavior of the instrument. Default Value: 0.0 seconds |

Notes
|
 |
error in (no error) The error in cluster can accept error information wired from VIs previously called. Use this information to decide if any functionality should be bypassed in the event of errors from other VIs.
The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed. |
 |
instrument handle out The instrument handle that you obtain from the IviDmm Initialize or IviDmm Initialize With Options VI. |
 |
error out The error out cluster passes error or warning information out of a VI to be used by other VIs.
The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed. |
