IviDownconverter Interchangeability
The IviDownconverter class driver performs interchangeability checking when you set the IviDownconverter Interchange Check property to VI_TRUE and you call one of the following VI:
IviDownconverter Wait Until Settled
In addition to the general interchangeability checking rules, the IviDownconverter class defines additional rules and exceptions for each capability group.
| IviDownconverterBase | If the IviDownconverter IF Output Enabled property is set to False, no other properties in the IviDownconverterBase capability group or in any extension group need to be in a user-specified state. If the IviDownconverter External LO Enabled property is set to False, then the IviDownconverter External LO Enabled property does not need to be in a user-specified state. |
| IviDownconverterBypass | If the IviDownconverter Bypass property is set to True, no properties in the IviDownconverterBase capability group or in any extension group need to be in a user-specified state. |
| IviDownconverterExternalMixer | If the IviDownconverter External Mixer Enabled property is set to False, then all remaining group properties do not need to be in a user-specified state. If the IviDownconverter External Mixer Bias Enabled property is set to False, then the IviDownconverter External Mixer Bias Level and IviDownconverter External Mixer Bias Limit properties do not need to be in a user-specified state. |
| IviDownconverterFrequencyStep | If the IviDownconverter Frequency Sweep Mode property is set to IVIDOWNCONVERTER_VAL_FREQUENCY_SWEEP_MODE_NONE, no property in the IviDownverterFrequencyStep extension group needs to be in a user-specified state. If the IviDownconverter Frequency Step Single Step Enabled property is set to True, the IviDownconverter Frequency Step Dwell property does not need to be in a user-specified state. If the IviDownconverterFrequencySweep extension group does not need to be checked for interchangeability, then properties in the IviDownconverterFrequencyStep extension group do not need to be in a user-specified state. |
| IviDownconverterFrequencySweep | If the IviDownconverter Frequency Sweep Mode property is set to IVIDOWNCONVERTER_VAL_FREQUENCY_SWEEP_MODE_NONE, no property in the IviDownverterFrequencySweep extension group needs to be in a user-specified state. If the IviDownconverter Frequency Sweep Mode property is set to a value other than IVIDOWNCONVERTER_VAL_FREQUENCY_SWEEP_MODE_SWEEP, no other properties besides IviDownconverter Frequency Sweep Trigger Source needs be in a user-specified state. |
| IviDownconverterFrequencySweepList | If the IviDownconverter Frequency Sweep Mode property is set to IVIDOWNCONVERTER_VAL_FREQUENCY_SWEEP_MODE_NONE, no property in the IviDownverterFrequencySweepList extension group needs to be in a user-specified state. If the IviDownconverter Frequency Step Single Step Enabled property is set to True, the IviDownconverter Frequency Step Dwell property does not need to be in a user-specified state. If the IviDownverterFrequencySweepList extension group does not need to be checked for interchangeability, then properties in the IviDownconverterFrequencyStep extension group need not be in a user-specified state. |
The IviCounter class does not define additional interchangeability rules or exceptions for the following extension capability groups: IviDownconverterBandCrossingInformation, IviDownconverterSoftwareTrigger, IviDownconverterIFFilter, IviDownconverterPreselector, IviDownconverterVideoDetectorBandwidth, IviDownconverterCalibration, and IviDownconverterReferenceOscillator.
