Owning Palette: Configuration

Configures the Payload Length Mode and Payload Length parameters that decide the length of the payload to be used for the measurement.

Instrument Handle In specifies the RFmx session refnum. Instrument Handle In is obtained from the RFmxInstr Initialize NIRFSA VI.

Payload Length Mode specifies the payload length mode of the signal to be measured. The Payload Length Mode and Payload Length parameters decide the length of the payload to be used for measurement. The default value is Auto.

Manual (0)

Enables the value specified by the Payload Length parameter. The acquisition and measurement durations will be decided based on this value.

Auto (1)

Enables the standard defined maximum payload length for the selected packet type. If this parameter is set to Auto, the maximum standard defined payload length for the selected packet type is chosen. For LE, the maximum payload length that a device under test(DUT) can generate varies from 37 to 255 bytes. When you set the payload length mode for the LE packet type to Auto, RFmx chooses 37 bytes as the payload length.

Payload Length specifies the payload length of the signal in bytes. The parameter is applicable only when you set the Payload Length Mode parameter to Manual. This parameter returns the payload length used for measurement if you set the Payload Length Mode parameter to Auto. The default value is 10.

Selector String specifies a selector string comprising of the signal name. If you do not specify the signal name, the default signal instance is used. The default value is "" (empty string).

Examples:

"signal::sig1"

You can use the RFmxBT Build Signal String VI to build the selector string.

error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

Instrument Handle Out passes a reference to your RFmx session to the next VI.

error out contains error information. This output provides standard error out functionality.
