Exceptions
| Exception | Condition |
|---|---|
| ObjectDisposedException | The PllFractionalModeEnabled property was accessed after the associated NIRfsg object was disposed. |
Remarks
Fractional mode provides a finer frequency step resolution and allows smaller values for the FrequencyStepSize property.
To use this property for the PXIe-5830/5831/5832, you must specify the the channelName of the RfsgChannelBasedLO 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
