Remarks


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-ohm impedance. A change in the device impedance may increase the VSWR value higher than the device specifications.

For PXIe-5830/5831/5832, input isolation is supported for all available ports for your hardware configuration.

You do not need to use a selector string if you want to configure this attribute for all signal instances. Specify the signal name in the selector string if you want to configure or read that signal instance. Refer to the Selector String topic for information about the string syntax.

The default value is Disabled.

Supported devices: PXIe-5644/5645/5646, PXIe-5663/5663E/5665/5668, PXIe-5820/5830/5831/5832/5840/5841/5842/5860
