IviPwrMeterTriggerSource Capability Group
C Function Prototype
ViStatus IviPwrMeter_ConfigureTriggerSource (ViSession vi, ViInt32 triggerSource);
Purpose
This function configures the trigger source of the power meter.
Parameters
| Name | Type | Description |
|---|---|---|
| vi | ViSession | The ViSession handle that you obtain from the IviPwrMeter_init or IviPwrMeter_InitWithOptions function. The handle identifies a particular instrument session. Default Value: None |
| triggerSource | ViInt32 | Specifies the trigger source. After you call either the IviPwrMeter_Read or the IviPwrMeter_Initiate function, the Power Meter waits for the trigger you specify. The driver sets the IVIPWRMETER_ATTR_TRIGGER_SOURCE attribute to this value. Defined Values: IVIPWRMETER_VAL_IMMEDIATE (Immediate) - The power meter exits the Wait-For-Trigger state immediately after entering. It does not wait for a trigger of any kind. IVIPWRMETER_VAL_EXTERNAL (External) - The power meter exits the Wait-For-Trigger state when an internal trigger event occurs on the measurement signal. IVIPWRMETER_VAL_INTERNAL (Internal) - The power meter exits the Wait-For-Trigger state when a trigger occurs on the external trigger input. IVIPWRMETER_VAL_SOFTWARE_TRIG (Software) - The power meter exits the Wait-For-Trigger state when it receives software trigger. IVIPWRMETER_VAL_TTL0 (TTL0) - The power meter exits the Wait-For-Trigger state when it receives a trigger on TTL0. IVIPWRMETER_VAL_TTL1 (TTL1) - The power meter exits the Wait-For-Trigger state when it receives a trigger on TTL1. IVIPWRMETER_VAL_TTL2 (TTL2) - The power meter exits the Wait-For-Trigger state when it receives a trigger on TTL2. IVIPWRMETER_VAL_TTL3 (TTL3) - The power meter exits the Wait-For-Trigger state when it receives a trigger on TTL3. IVIPWRMETER_VAL_TTL4 (TTL4) - The power meter exits the Wait-For-Trigger state when it receives a trigger on TTL4. IVIPWRMETER_VAL_TTL5 (TTL5) - The power meter exits the Wait-For-Trigger state when it receives a trigger on TTL5. IVIPWRMETER_VAL_TTL6 (TTL6) - The power meter exits the Wait-For-Trigger state when it receives a trigger on TTL6. IVIPWRMETER_VAL_TTL7 (TTL7) - The power meter exits the Wait-For-Trigger state when it receives a trigger on TTL7. IVIPWRMETER_VAL_ECL0 (ECL0) - The power meter exits the Wait-For-Trigger state when it receives a trigger on ECL0. IVIPWRMETER_VAL_ECL1 (ECL1) - The power meter exits the Wait-For-Trigger state when it receives a trigger on ECL1. IVIPWRMETER_VAL_PXI_STAR (PXI Star) - The power meter exits the Wait-For-Trigger state when it receives a trigger on PXI Star trigger bus. IVIPWRMETER_VAL_RTSI_0 (RTSI0) - The power meter exits the Wait-For-Trigger state when it receives a trigger on RTSI0 line. IVIPWRMETER_VAL_RTSI_1 (RTSI1) - The power meter exits the Wait-For-Trigger state when it receives a trigger on RTSI1 line. IVIPWRMETER_VAL_RTSI_2 (RTSI2) - The power meter exits the Wait-For-Trigger state when it receives a trigger on RTSI2 line. IVIPWRMETER_VAL_RTSI_3 (RTSI3) - The power meter exits the Wait-For-Trigger state when it receives a trigger on RTSI3 line. IVIPWRMETER_VAL_RTSI_4 (RTSI4) - The power meter exits the Wait-For-Trigger state when it receives a trigger on RTSI4 line. IVIPWRMETER_VAL_RTSI_5 (RTSI5) - The power meter exits the Wait-For-Trigger state when it receives a trigger on RTSI5 line. IVIPWRMETER_VAL_RTSI_6 (RTSI6) - The power meter exits the Wait-For-Trigger state when it receives a trigger on RTSI6 line. Default Value: IVIPWRMETER_VAL_IMMEDIATE (Immediate) |
