Fetches the peak power of the preamble fields.
Use "segment(n)/chain(k)" as the selector string to read results from this method.

Syntax

Namespace: NationalInstruments.RFmx.WlanMX

public int FetchPreamblePeakPowersCommon(string selectorString, double timeout, out double lStfPeakPowerMaximum, out double lLtfPeakPowerMaximum, out double lSigPeakPowerMaximum)

Parameters

NameTypeDescription
selectorStringstring

Specifies a selector string comprising of the result name, segment number, and chain number. If you do not specify the result name, the default result instance is used. Example:
"segment0/chain0"
"result::r1/segment0/chain0"
You can use the BuildChainString(string, int) method to build the selector string.

timeoutdouble

Specifies the timeout 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 method waits until the measurement is complete. This value is expressed in seconds.

lStfPeakPowerMaximumout double

Upon return, contains the peak power of the L-STF or STF field. When you set the SetAveragingEnabled(string, RFmxWlanMXOfdmModAccAveragingEnabled) method to True , this parameter returns the maximum of the L-STF or STF peak power results computed for each averaging count. This value is expressed in dBm.

lLtfPeakPowerMaximumout double

Upon return, contains the peak power of the L-LTF or LTF field. When you set the OFDMModAccAveragingEnabled method to True , this parameter returns the maximum of the L-LTF or LTF peak power results computed for each averaging count. This value is expressed in dBm.

lSigPeakPowerMaximumout double

Upon return, contains the peak power of the L-SIG or SIGNAL field. When you set the OFDMModAccAveragingEnabled method to True , this parameter returns the maximum of the L-SIG or SIGNAL field peak power results computed for each averaging count. This value is expressed in dBm.

Returns

Returns the status code of this method. The status code either indicates success or describes a warning condition.
