This function can be call using the [F12] key.

Opens a form in order to initiate analysis of the Radio link from a point to a point.
The points in this analysis are objects and retrieved from a network. Also it is possible to analyse from the transmitter to any point on the radio link. This point has to be clicked on by the mouse.

Window types

The radio link tool enables to evaluate a radio link. All relevant information is displayed in this tool.
The radio link tool displays in formation in 4 ways:

• Profile
• Details
• Range
• Distribution

On the bottom of the window the Transmitter, Receiver, Net and frequency are displayed.

Relation of the radio link to the current map window

The radio link is directly coupled to the current map window and displays on the map the analysed radio link.

Swap function

The swap function swaps the TX and RX unit.

Frequency

Initial the frequency is copied from the 'Network properties - Parameters' but can be changed to the meet the requirements for the analysis.

Net

This is the net in which both Transmitter and receiver are member. When Transmitter and receiverare member of more Nets those nets can be selected.

All values in the Transmitter and Receiver plane are related to the link budget. See 'how to > Link budgets'

Transmitter

This information applies to the Transmitter in the evaluated link.

Signal meter bar
This 'S-meter' displays the RSSI of the receivers station at the Transmitter location. The Setting of the S-meter can be configured at 'Options - S-Unit'

Unit
Through a pull-down menu the required Transmitting unit can be selected.

Role
The role that the Transmitting unit has. This is set in 'Network properties - Membership > Role of unit'

TX system name
The System name that is applied to the unit. The system is applied to the unit in in 'Network propererties - Membership' and the system is configured in 'Network properties - Systems'

TX Power
TX power of the transmitting unit as applied to the unit by the selected system. The power is expressed in Watts and dB.

Line Loss
Line loss in dB between the transmitter and the antenna of the transmitting unit as applied to the unit by the selected system.

Antenna gain
Using the [+] button the applied antenna pattern can be viewed. The purple line in the antenna pattern viewer displays the direction of the radio link with respect to the unit.

Radiated Power
The Radiated power in Eirp and Erp in Watt

Antenna Height (m)
Using the [-] and [+] button the antenna height can be altered in 0.1 meter steps. Also it is possible to enter the antenna height directly.

Undo
When the antenna height is changed in the Radio Link window the [undo] button enables. Using the undo button the antenna height is reset to the value as specified in 'Network properties - Systems'

Receiver

This information applies to the Transmitter in the evaluated link.

Signal meter bar
This 'S-meter' displays the RSSI of the receivers station at the Transmitter location. The Setting of the S-meter can be configured at 'Options - S-Unit'

Unit
Through a pull-down menu the required Transmitting unit can be selected.

Role
The role that the Transmitting unit has. This is set in 'Network properties - Membership > Role of unit'

RX system name
The System name that is applied to the unit. The system is applied to the unit in in 'Network propererties - Membership' and the system is configured in 'Network properties - Systems'

Required E-Field
The by the receiver required E-field in dB(uV/m). This is the real fieldstrength required at the antenna and is calculated from RX sensitivity, line loss, and antenna gain.

Antenna gain
Using the [+] button the applied antenna pattern can be viewed. The purple line in the antenna pattern viewer displays the direction of the radio link with respectto the unit.

RX Sensitivity
RX Sensitivity of the receiver in uV and dBm at 50 ohms.

Antenna Height (m)
Using the [-] and [+] button the antenna height can be altered in 0.1 meter steps. Also it is possible to enter the antenna height directly.
