Glossary Item Box

Gets or sets the X dB bandwidth threshold to use in dB when computing the signal bandwidth when OBW is active (IsObwVisible is set to true).

Syntax

Visual Basic (Declaration) 
Public Overridable Property XDecibelBandwidthThreshold As Double
C# 
public virtual double XDecibelBandwidthThreshold {get; set;}
C++/CLI 
public:
virtual property double XDecibelBandwidthThreshold {
   double get();
   void set (    double value);
}

Remarks

The signal bandwidth is computed based upon the peak in a frequency domain trace where the peak is the bin with the highest value (interpolation is not currently used to find the peak value so ensure there is enough resolution to the bins in the frequency domain trace for the accuracy desired). Simple linear interpolation is used when finding the locations that first cross the threshold value (relative to the peak value) when they are not exactly on bin. Bins close to DC are ignored in order to still be able to measure signal bandwidths in the presence of a large DC component.

Requirements

Target Platforms: Windows 11 Professional or Enterprise; Windows 10 Professional, Enterprise, or Education (64-bit)

Minimum Software Version Requirement: Keysight PathWave 89600 VSA Ver 29.40
