If a LFTX card is installed, you can read the following parameters:
| Parameter Name | Description |
|---|---|
| Opt. Pwr | This parameter shows the received optical power. The colour code of this parameter tells you, if the value is in the range (green) or not (red). The values are given by the LFTX card and can not be changed. |
| RF Pwr | This value shows the input RF power of the LFTX card. The measurement range is approx. -45...0dBm (range varies by changing RF offset on Setup page and gain setting. Provided values are valid for RF offset = -61dB and gain setting = 0dB). |
| Diode RF Pwr | This value shows the input RF power of the LFTX cards to the Laser-diode. The colour code of this parameter tells you if the value is in range (green) or not (orange). The values are given by the LFTX card and can not be changed.. If a 'Warning' is displayed, the summary state of this slot is nevertheless 'OK', because this is not a fault. Alarm threshold values are: RFmin typ. -23dBm (-25...-20dBm), RFmax typ. -10dBm (-11...-5dBm) |
| RF Thresh. | The RF threshold is a parameter that can bet set to any value >=-99dBm in the configuration menu. If the current RF power is below the RF threshold it shows a (red) value to indicate a fault. If the RF power is above the limit it shows a (green) value. Software-limits configuration: <-90dBm will disable the Threshold Alarm, <-95dBm will also disable the RF-card Alarm/Warning (Hardware Limit Card) at the Web-page and the remote interface. This is the second of 2 redundancy switching criteria (if the redundancy switching option is installed and activated). When this value falls below configured threshold value, redundancy switching will be initiated. |
| LNB curr. | If the chassis is configured to supply LNCs, the actual current is shown here for every slot. The current limits can be changed on the 'Config' menu. If the current is within this range, a green 'OK' is shown, if the value is out of the range, a red 'FLT' is displayed here. |
| Remote | It is possible to change some settings of the LFTX card remote (e.g. via web browser interface) or local (only on the front panel of the card). The current state of the hardware remote/local switch on the corresponding card is shown here. |
| Gain | An integrated attenuator makes it possible to attenuate the RF-signal in 1dB-steps from -16 to +15dB. The selected value is displayed here. If the parameter 'Remote' is 'ON', you can easily change the attenuation value by clicking on the '+' '-' buttons. If the parameter 'Remote' is 'OFF' it is not possible to change this parameter by remote control. |
