Description
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 attribute, 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 attribute to NIRFSG_VAL_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. |
PXIe-5645: This attribute is ignored if you are using the I/Q ports.
PXIe-5840/5841: RF blanking does not occur for frequencies below 120 MHz.
For PXIe-5830/5831/5832: The RF Blanking reserves a PXI trigger line. If you are calling any niRFSG_reset or niRFSA_reset on the same device, NI recommends calling it before committing blanking attributes. Alternatively, you can call niRFSG_ResetWithOptions or niRFSA_ResetWithOptions. Select Routes in the steps to omitparameter.
Valid Values:
| "" (empty string) | RF blanking is disabled. |
| NIRFSG_VAL_MARKER0 | RF blanking is tied to marker0. |
| NIRFSG_VAL_MARKER1 | RF blanking is tied to marker1. |
| NIRFSG_VAL_MARKER2 | RF blanking is tied to marker2. |
| NIRFSG_VAL_MARKER3 | RF blanking is tied to marker3. |
Default Value: "" (empty string)
Supported Devices: PXIe-5644/5645/5646, PXIe-5830/5831/5832/5840/5841
