Remarks
PXIe-5830/5831/5832: To use this property, you must specify the the channelName of the RfsaChannelBasedLO sub-object to specify the name of the channel you are configuring. You can configure the LO1 and LO2 channels by using lo1 or lo2, 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).
An active channel can be passed using the indexer ItemString
For the PXIe-5831 with PXIe-5653 and PXIe-5832 with PXIe-5653, this attribute is ignored if the PXIe-5653 is used as the LO source.
Fractional mode gives a finer frequency step resolution, but it may result in non-harmonic spurs. Refer to the NI PXIe-5644R Specifications or the NI PXIe-5645R Specifications for more information about fractional mode and non-harmonic spurs.
