Description
Specifies whether to enable the LO OUT terminals on the installed devices.
PXIe-5601—The only valid value for this attribute is VI_TRUE.
PXIe-5603/5605/5606—If you want to daisy-chain multiple devices together using the same LO source, set this attribute to TRUE to export the LO input signals on the LO1 IN, LO2 IN, and LO3 IN terminals to LO1 OUT, LO2 OUT, and LO3 OUT, respectively.
PXIe-5694—You can enable this attribute only if you set the NIRFSA_ATTR_LO_SOURCE attribute to NIRFSA_VAL_LO_IN_STR, or if you set the NIRFSA_ATTR_LO_SOURCE attribute to NIRFSA_VAL_ONBOARD_STR and the NIRFSA_ATTR_IF_CONDITIONING_DOWN_CONVERSION_ENABLED attribute to NIRFSA_VAL_ENABLED.
PXIe-5830/5831—To use this attribute for the PXIe-5830/5831/5832, you must use the channelName parameter of the niRFSA_SetAttributeViBoolean function to specify the name of the channel you are configuring. You can configure the LO1 and LO2 channels by using lo1 or lo2 as the channel string, or set the channel string to lo1,lo2 to configure both channels. For all other devices, the only valid value for the channel string is "" (empty string).

Note If you are sharing an LO for the PXIe-5830/5831/5832 between an NI-RFSA and NI-RFSG session, ensure both sessions use the same shared setting. |
| VI_TRUE | Enables the LO OUT terminals. |
| VI_FALSE | Disables the LO OUT terminals. |
