IviRFSigGen_ConfigureSweep
IviRFSigGenSweep Capability Group
C Function Prototype
ViStatus IviRFSigGen_ConfigureSweep (ViSession vi, ViInt32 mode, ViInt32 triggerSource);
Purpose
This function configures the signal generator sweep mode and trigger source.
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 |
| mode | ViInt32 | Specifies the sweep mode applied to the output signal. The driver uses this value to set the IVIRFSIGGEN_ATTR_SWEEP_MODE attribute. Defined Values: IVIRFSIGGEN_VAL_SWEEP_MODE_NONE - The RF output of the signal generator is a non-swept signal (Continuous Wave) using the frequency and power/level specified in the IviRFSigGen_ConfigureRF function. IVIRFSIGGEN_VAL_SWEEP_MODE_FREQUENCY_SWEEP - The signal generator sweeps the RF output signal's frequency in an analog form (non-stepped). IVIRFSIGGEN_VAL_SWEEP_MODE_POWER_SWEEP - The signal generator sweeps the RF output signal's power in an analog form (non-stepped). IVIRFSIGGEN_VAL_SWEEP_MODE_FREQUENCY_STEP - The signal generator sweeps the RF output signals frequency in steps. IVIRFSIGGEN_VAL_SWEEP_MODE_POWER_STEP - The signal generator sweeps the RF output signals power level in steps. IVIRFSIGGEN_VAL_SWEEP_MODE_LIST - The signal generator uses two lists with frequency and power level values to sweep the RF output signals. Default Value: IVIRFSIGGEN_VAL_SWEEP_MODE_NONE |
| triggerSource | ViInt32 | Specifies the trigger used to start a sweep operation. The driver uses this value to set the IVIRFSIGGEN_ATTR_SWEEP_TRIGGER_SOURCE attribute. Defined Values: IVIRFSIGGEN_VAL_SWEEP_TRIGGER_SOURCE_IMMEDIATE - The sweep system does not wait for a trigger of any kind, so it is running continuously. IVIRFSIGGEN_VAL_SWEEP_TRIGGER_SOURCE_EXTERNAL - The sweep is started with an external signal. IVIRFSIGGEN_VAL_SWEEP_TRIGGER_SOURCE_SOFTWARE - The sweep is started with a software programmable trigger. Default Value: IVIRFSIGGEN_VAL_SWEEP_TRIGGER_SOURCE_IMMEDIATE |
