Specific Attribute
| Data type |
Access | High Level Functions |
|---|---|---|
| ViInt32 | R/W | None |
Description
Specifies whether input isolation is enabled.
Enabling this attribute isolates the input signal at the RF IN connector on the RF downconverter from the rest of the RF downconverter signal path. Disabling this attribute reintegrates the input signal into the RF downconverter signal path.
 |
Note If you enable input isolation for your device, the device impedance is changed from the characteristic 50 Ω impedance. A change in the device impedance may also cause a VSWR value higher than the device specifications. |
For the PXIe-5830/5831/5832, input isolation is supported for all available ports for your hardware configuration.
Defined Values:| NIRFSA_VAL_ENABLED | Enables input isolation on the RF downconverter. |
| NIRFSA_VAL_DISABLED | Disables input isolation on the RF downconverter. |
Default Value: NIRFSA_VAL_DISABLED, if the device configuration is supported.
Supported Devices: PXIe-5601/5603/5605/5606 (external digitizer mode), PXIe-5644/5645/5646, PXIe-5663/5663E/5665/5667/5668, PXIe-5693, PXIe-5820/5830/5831/5832/5840/5841
