IviRFSigGen_ConfigurePulse
IviRFSigGenPulseGenerator Capability Group
C Function Prototype
ViStatus IviRFSigGen_ConfigurePulse (ViSession vi, ViInt32 triggerSource, ViReal64 pulseWidth, ViBoolean gatingEnabled);
Purpose
This function configures the trigger source, pulse width, and gating enabled for the pulse generator within the RF signal generator.
Parameters
| Name | Type | Description |
|---|---|---|
| vi | ViSession | The ViSession handle that you obtain from the IviRFSigGen_init or IviRFSigGen_InitWithOptions function. The handle identifies a particular instrument session. Default Value: None |
| triggerSource | ViInt32 | Specifies the source of the signal the pulse generator uses to generate one pulse. The driver uses this value to set the IVIRFSIGGEN_ATTR_PULSE_TRIGGER_SOURCE attribute. Defined Values: IVIRFSIGGEN_VAL_PULSE_TRIGGER_SOURCE_INTERNAL - No external trigger is used. The pulse period is specified by the IVIRFSIGGEN_ATTR_PULSE_INTERNAL_TRIGGER_PERIOD attribute. IVIRFSIGGEN_VAL_PULSE_TRIGGER_SOURCE_EXTERNAL - The pulse is started with a trigger after the delay time specified by the IVIRFSIGGEN_ATTR_PULSE_EXTERNAL_TRIGGER_DELAY attribute. Default Value: IVIRFSIGGEN_VAL_PULSE_TRIGGER_SOURCE_INTERNAL |
| pulseWidth | ViReal64 | Specifies the width of the output pulse. The driver uses this value to set the IVIRFSIGGEN_ATTR_PULSE_WIDTH attribute. Units: Seconds Default Value: 50.0e-6 seconds |
| gatingEnabled | ViBoolean | Enables pulse gating. The driver uses this value to set the IVIRFSIGGEN_ATTR_PULSE_GATING_ENABLED attribute. Valid Values: VI_TRUE; VI_FALSE Default Value: VI_FALSE |
