IviDmm Configure Trigger
IviDmm Base Capability Group
This VI configures the common DMM trigger properties. These properties are the trigger source and trigger delay.
 |
instrument handle The instrument handle that you obtain from the IviDmm Initialize or IviDmm Initialize With Options VI. |
 |
trigger source (Immediate) Specify the trigger source you want to use. The driver sets the
IviDmm Trigger Source property to this value. After you call the Read or Initiate VI,the DMM waits for the trigger you specify in this parameter. After it receives the trigger, the DMM waits the length of time you specify in the Trigger Delay parameter. The DMM then takes a measurement. Valid Values: IVIDMM_VAL_IMMEDIATE—Immediate IVIDMM_VAL_EXTERNAL—External IVIDMM_VAL_SOFTWARE_TRIG—Software Trigger Function 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_ECL—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
|
 |
trigger delay (0.0 s) Pass the value you want to use for the trigger delay. Express this value in seconds. The driver sets the IviDmm Trigger Delay property to this value.
The trigger delay specifies the length of time the DMM waits after it receives the trigger and before it takes a measurement. Use positive values to set the trigger delay in seconds. The driver reserves negative values for configuring the DMM to calculate the trigger delay automatically. 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. |
