RFmxBT ModAcc Fetch DEVM Magnitude Error VI
- Updated2025-10-13
- 3 minute(s) read
Fetches ModAcc RMS magnitude error results. These results are valid only for enhanced data rate (EDR) packets.

Inputs/Outputs
Selector String
—
Selector String specifies a selector string comprising of the signal name and the result name. 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. The default value is "" (empty string). Example: "signal::sig1" "result::r1" "signal::sig1/result::r1" You can use the RFmxBT Build Signal 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.
Average RMS Magnitude Error Mean (%)
—
Average RMS Magnitude Error Mean returns the average of the RMS magnitude error values computed on each 50 us block of EDR portion of the EDR packet. When you set the ModAcc Averaging Enabled property to True, it returns the mean of the average RMS magnitude error values computed for each averaging count. This value is expressed as a percentage.
Peak RMS Magnitude Error Maximum (%)
—
Peak RMS Magnitude Error Maximum returns the peak of the RMS magnitude error values computed on each 50 us block of EDR portion of the EDR packet. When you set the ModAcc Averaging Enabled property to True, it returns the maximum of the peak RMS magnitude error values 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. |
