RFmxBT ModAcc Fetch Frequency Error (BR) VI

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

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 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.

Initial Frequency Error Maximum returns the initial frequency error value computed on the preamble of the BR packet. When you set the ModAcc Averaging Enabled property to True, it returns a value corresponding to the maximum of absolute initial frequency error values computed for each averaging count. This value is expressed in Hz.

Peak Frequency Drift Maximum returns the peak frequency drift value computed on the BR packet. When you set the ModAcc Averaging Enabled property to True, it returns the value corresponding to the maximum of absolute peak frequency drift values computed for each averaging count. This value is expressed in Hz.

Peak Frequency Drift Rate Maximum returns the peak frequency drift rate value computed on the BR packet. When you set the ModAcc Averaging Enabled property to True, it returns the value corresponding to the maximum of absolute peak frequency drift rate values computed for each averaging count. This value is expressed in Hz.

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