Glossary Item Box

Gets the total number of input data samples the user must supply in order to satisfy the configured measurement.

Syntax

Visual Basic (Declaration) 
Public ReadOnly Property RequiredInputDataPoints As Long
C# 
public long RequiredInputDataPoints {get;}
C++/CLI 
public:
property int64 RequiredInputDataPoints {
   int64 get();
}

Remarks

This calculated value represents one of the following: (a) The total number of required input time domain data samples when InputDataDomain is InputDataDomain.Time. (b) The total number of required input OFDM (subcarrier frequency) domain data samples when InputDataDomain is InputDataDomain.Ofdm.

When InputDataDomain is InputDataDomain.Time, the calculated time domain data samples value is partly determined by the ResultLengthInSlots in combination with the RequirementsForTimeDomainInputData.SampleRate. The calculated value also includes any additional search interval samples required to reliably find the frame boundary, the size of which depends on both the periodicity of the synchronization signal being searched for, and whether the frame trigger is enabled when capturing the data. In addition, the calculated value also includes RequirementsForTimeDomainInputData.SettlePoints which represents the sum of any additional pre-settling (delay) and post-settling samples required to settle the measurement filtering used in the demodulation process. To summarize, RequiredInputDataPoints directly depends on the sample point requirements of ResultLengthInSlots + Search Interval + RequirementsForTimeDomainInputData.SettlePoints.

When InputDataDomain is InputDataDomain.Ofdm, the calculated OFDM (subcarrier frequency) domain data samples value is determined by equation RequirementsForOfdmDomainInputData.NumberOfSubcarriers multiplied by RequirementsForOfdmDomainInputData.NumberOfSymbols. Where the RequirementsForOfdmDomainInputData.NumberOfSymbols depends on both ResultLengthInSlots and CyclicPrefixLength. To summarize, RequiredInputDataPoints = RequirementsForOfdmDomainInputData.NumberOfSubcarriers * RequirementsForOfdmDomainInputData.NumberOfSymbols.
