AngleOfArrival Class

Vision™ MX280001A Spectrum Monitoring Application Programming Interface : Vision API Reference : AngleOfArrival Class

Properties

AngleOfArrival.AntennaAngle Property

Gets or sets the mid-line direction of the antenna as degrees from true North measured clock-wise.

Public Property AntennaAngle(ByVal Index As Integer) As Integer

[System.Runtime.CompilerServices.IndexerName("AntennaAngle")]
public int this[int Index] {get; set;}

C++

[System.Runtime.CompilerServices.IndexerName("AntennaAngle")]
public int this[int Index] {get; set;}

Parameters

Index: Index of the antenna being set.

Remarks

Angle of arrival assumes three antennas on the same tower, each looking at in different directions, or sectors. The sectors are at 120 degree intervals, thus seeing a full 360 degree circle.

AngleOfArrival.DegreeMinuteSecond Property

Gets or sets the format of GPS coordinate.

Public Property DegreeMinuteSecond() As Boolean

public bool DegreeMinuteSecond {get; set;}

C++

public bool DegreeMinuteSecond {get; set;}

Remarks

GPS coordinates are given in degrees. If AngleOfArrival.DegreeMinuteSecond is True, then the format is: dd° mm’ ss.ss” If AngleOfArrival.DegreeMinuteSecond is False, then the format is in decimal, ie. dd.ddddd

AngleOfArrival.GPSCoordinates Property

Does an immediate query to the monitor for updated GPS location.

Public Property GPSCoordinates() As PointF

public PointF GPSCoordinates {get; set;}

C++

public PointF GPSCoordinates {get; set;}

AngleOfArrival.Hostname Property

Enter the hostname or URL address for the instrument taking measurements.

Public Property Hostname() As String

public string Hostname {get; set;}

C++

public string Hostname {get; set;}

AngleOfArrival.Location Property

Gets the Power-On-Arrival location estimate as a set of GPS coordinates.

Public ReadOnly Property Location() As AOA_Result

public AOA_Result Location {get;}

C++

public AOA_Result Location {get;}

Remarks

This Property may return an invalid or useless value if the measurement has not already been properly set up. Before reading the Location, you must set the datasource and the interferer frequency, at least.

AngleOfArrival.MeassuredPower Property

Gets or sets the measured power value set in Parameters.

Public Property MeassuredPower(ByVal Index As Integer) As Single

[System.Runtime.CompilerServices.IndexerName("MeassuredPower")]
public float this[int Index] {get; set;}

C++

[System.Runtime.CompilerServices.IndexerName("MeassuredPower")]
public float this[int Index] {get; set;}

Parameters

Index: Index of the antenna being set.

AngleOfArrival.ReferenceLevel Property

Gets or sets the reference level amplitude value.

Public Property ReferenceLevel() As Single

public float ReferenceLevel {get; set;}

C++

public float ReferenceLevel {get; set;}

AngleOfArrival.SourceFrequency Property

Gets or sets the frequency of the source of interference.

Public Property SourceFrequency() As Double

public double SourceFrequency {get; set;}

C++

public double SourceFrequency {get; set;}

AngleOfArrival.SourceMode Property

Gets or sets the Source Mode: power at reference frequency, sweep traces from which Vision will extract the power at the source frequency, or live trace mode where Vision will extract the power at the source frequency.

Public Property SourceMode() As PowerSource

public PowerSource SourceMode {get; set;}

C++

public PowerSource SourceMode {get; set;}

AngleOfArrival.StartFrequency Property

Gets or sets the start frequency for the active remote spectrum monitor.

Public Property StartFrequency() As Double

public double StartFrequency {get; set;}

C++

public double StartFrequency {get; set;}

AngleOfArrival.StopFrequency Property

Gets or sets Stop Frequency of the active remote spectrum monitor.

Public Property StopFrequency() As Double

public double StopFrequency {get; set;}

C++

public double StopFrequency {get; set;}

AngleOfArrival.Trace Property

Gets or sets the trace of the specified channel set in parameters.

Public Property Trace(ByVal Index As Integer) As String

[System.Runtime.CompilerServices.IndexerName("Trace")]
public string this[int Index] {get; set;}

C++

[System.Runtime.CompilerServices.IndexerName("Trace")]
public string this[int Index] {get; set;}

Parameters

Index: Index of the antenna being set.

Methods

AngleOfArrival.VerifySource Method

Gets status of Verify Source to set the correct type of angle of arrival calculation depending on the source mode setting.

Public Function VerifySource() As Boolean

public bool VerifySource()

C++

public bool VerifySource()

Fields

Angle Field

The angle, measured from North, along which the interferer is located.

Public Angle As Integer

public int Angle

C++

public int Angle

Latitude Field

The latitude coordinate of the remote spectrum monitor.

Public Latitude As Single

public float Latitude

C++

public float Latitude

Longitude Field

The longitude coordinate of the remote spectrum monitor.

Public Longitude As Single

public float Longitude

C++

public float Longitude

Width Field

The width, in degrees, of the location estimation. This can be thought of as a pie wedge whose point is centered at the remote spectrum monitor and that extends out in the direction of the interferer. The width indicates a measure of uncertainty in the location estimate.

Public Width As Integer

public int Width

C++

public int Width

Direction Field

If this is a directional antenna, perhaps a sector on a cell phone tower, for instance, this value indicates the direction angle from true north for the center line of the antenna sector. Due East is at 90 degrees.

Public Direction As Integer

public int Direction

C++

public int Direction

Height Field

The height location of the remote spectrum monitor.

Public Height As Integer

public int Height

C++

public int Height

Enumerations

PowerSource Enumeration

Designates the mode for Angle-of-Arrival and Power-on-Arrival location estimation.

Value

PowerSource Values and Definitions
Value	Definition
Power	User supplies Power values for each probe at the designated frequency
Trace	User supplies sweep traces for each probe. Vision extracts the power at the designated frequency.
Live	User supplies URLs for each probe. Vision captures sweep traces from each and extracts the power at the designated frequency.
