RFmxBT TXP Fetch LE CTE Transmit Slot Powers VI
- Updated2025-10-13
- 3 minute(s) read
Fetches the transmit power (TXP) measurement results over each transmit slot of the constant tone extension (CTE) portion for low energy (LE) packets when you set the Direction Finding Mode property to Angle of Departure.

Inputs/Outputs
Selector String
—
Selector String specifies a selector string comprising of the signal name, result name, and slot number. If you do not specify the signal name, the default signal instance is used. If you do not specify the result name, the default result instance is used. Example: "slot0" "signal::sig1/slot0" "signal::sig1/result::r1/slot0" "result::r1/slot0" You can use the RFmxBT Build Slot String VI to build the selector string.
Instrument Handle In
—
Instrument Handle In specifies the RFmx session refnum. Instrument Handle In is obtained from the RFmxInstr Initialize NIRFSA VI.
Timeout (s)
—
Timeout specifies the timeout for fetching the specified measurement. This value is expressed in seconds. Set this value to an appropriate time, longer than expected for fetching the measurement. A value of -1 specifies that the VI waits until the measurement is complete. The default value is 10.
error in (no error)
—
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
Instrument Handle Out
—
Instrument Handle Out passes a reference to your RFmx session to the next VI.
Transmit Slot Average Power Mean (dBm)
—
Transmit Slot Average Power Mean returns the average power computed over each transmit slot in CTE portion of the LE packet. When you set the TXP�Averaging�Enabled property to True, it returns the mean of the CTE transmit slot average power results computed for each averaging count. This value is expressed in dBm.
Transmit Slot Peak Absolute Power Deviation Maximum (%)
—
Transmit Slot Peak Absolute Power Deviation Maximum returns the peak absolute power deviation computed over each transmit slot in the CTE portion of the LE packet. The peak absolute power deviation is the deviation of peak power in each transmit slot with respect to the average power in that transmit slot. When you set the TXP�Averaging�Enabled property to True, it returns the maximum of the CTE transmit slot absolute power deviation results computed for each averaging count. This value is expressed as a percentage.
error out
—
error out contains error information. This output provides standard error out functionality. |
