Fetches an array of peak powers of the lower and upper intermods.

Inputs/Outputs
Selector String
—
Selector String specifies a selector string comprising of the signal name and 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 RFmxSpecAn 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, in seconds, for fetching the specified measurement. 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 of your RFmx session to the next VI.
Intermod Order
—
Intermod Order returns an array of the orders of the intermods.
Lower Intermod Absolute Power (dBm)
—
Lower Intermod Absolute Power returns an array of the peak power values measured around the lower intermod frequency when you set the IM Local Peak Search Enabled property to True. This value is expressed in dBm. When you set the IM Local Peak Search Enabled property to False, the measurement returns the power at the lower intermod frequency.
Upper Intermod Absolute Power (dBm)
—
Upper Intermod Absolute Power returns an array of the peak power values measured around the upper intermod frequency when you set the IM Local Peak Search Enabled property to True. This value is expressed in dBm. When you set the IM Local Peak Search Enabled property to False, the measurement returns the power at the upper intermod frequency.
error out
—
error out contains error information. This output provides standard error out functionality. |
