Description
Specifies whether to enable the RF IN LO OUT terminal on the PXIe-5840/5841.
Set this attribute to NIRFSG_VAL_ENABLE to export the LO signal from the RF IN LO OUT terminal.
When this attribute is enabled, if the NIRFSG_ATTR_LO_SOURCE attribute is set to NIRFSG_VAL_LO_IN_STR and you do not set the NIRFSG_ATTR_LO_FREQUENCY or NIRFSG_ATTR_UPCONVERTER_CENTER_FREQUENCY attributes, NI-RFSG rounds the LO frequency to approximately an LO step size as if the source was NIRFSG_VAL_ONBOARD_STR. This ensures that when you configure NI-RFSA and NI-RFSG with compatible settings that result in the same LO frequency, the rounding also is compatible.
Defined Values:| NIRFSG_VAL_DISABLE | The RF In local oscillator signal is not present at the front panel LO OUT connector. |
| NIRFSG_VAL_ENABLE | The RF In local oscillator signal is present at the front panel LO OUT connector. |
| NIRFSG_VAL_UNSPECIFIED | The RF IN local oscillator signal may or may not be present at the front panel LO OUT connector, because NI-RFSA may be controlling it. |
Default Value: NIRFSA_VAL_UNSPECIFIED
Supported Devices: PXIe-5840/5841/5842
