Short Name: RF Blanking Source
Property of niRFSG
Specifies the Marker Event at which RF blanking occurs. RF blanking quickly attenuates the RF OUT signal. Use Marker Events to toggle the state of RF blanking. The RF Output always starts in the unblanked state.
To set this property, the NI-RFSG device must be in the Configuration state.
You can specify Marker Events by using scripts to trigger blanking at a certain point in a waveform. For example, if you set this property to marker0, and marker0 occurs on samples 1,000 and 2,000 of a script, then the RF Output will be blanked (attenuated) between samples 1,000 and 2,000.
|Note The shortest supported blanking interval is eight microseconds.|
|Note For the PXIe-5645, this property is ignored if you are using the I/Q ports.|
|Note For the PXIe-5840, RF blanking does not occur for frequencies less than 120 MHz.|
Supported Devices: PXIe-5644/5645/5646, PXIe-5840
Default Value: "" (empty string)
|"" (empty string)||RF blanking is disabled.|
|marker0||RF blanking is tied to marker0 event.|
|marker1||RF blanking is tied to marker1 event.|
|marker2||RF blanking is tied to marker2 event.|
|marker3||RF blanking is tied to marker3 event.|
