The LineUp-Control logical device supports the operator with the carrier line-up process. While intended to be used with the TX-LineSettings-CDB device, it can also be used stand alone.
The device lets the operator control the parameters EIRP and RF-ON. The modulator can be switched between modulated and c/w output.
'nominal eirp' contains the nominals EIRP as defined in the line settings database. For stand alone operation of the LineUp-Control device the value may be entered manually.
'lineup eirp' contains the reduced transmit power value which is used to start the line up process. This value also is set by the TX-LineSettings-CDB device from the line settings database, may be entered manually as well.
The next value is the actual EIRP setting of the HPA / transmit power control loop, followed by the measured EIRP value. Controls for RF ON/OFF and the c/w setting complete the LineUp-Control device screen.
Device window pages
The following table shows which device window pages are available with this individual device type. Tool-bar functions not mentioned here are described at the general description of device windows .
--- Brings up the device screen shown above.
--- The device info page.
--- The maintenance / configuration pageConfiguration parameters
At the maintenance page of the device window there are a couple of configuration parameters which must be set to integrate the device into the VLC/M&C.
| parameter | description |
|---|---|
| eirpSetId | The ID of the parameter which controls the EIRP. This typically may be something like 'EIRP-1.eirp'. |
| eirpMeasId | The ID of the parameter which reports the measured EIRP. May be something like 'EIRP-1.measuredEirp'. |
| rfOnId | The ID of the parameter controlling the carrier on/off state. |
| cwModeId | The ID of the modulator parameter which switches between modulated an c/w output. |
Remarks
When used with a TX-LineSettings-CDB device, the latter must be configured to send the nominal EIRP value to the 'nominalEirp' parameter and the reduced EIRP value to the'lineUpEirp' parameter of this device.
