The 'Readings' page is the main page of the beacon receiver which shows the actual measurement values and some important settings. Parameter settings reported here, are for information only. To change a setting switch to the Settings page. The 'Readings' page automatically refreshes once a second. The table below describes the information shown by this page:
| Parameter Name | Description |
|---|---|
| Input level | This is the actual signal level at the receiver's L-band input. When operating on one of the C/N measurement modes, this field shows the actual C/N or C/N0. |
| Frequency | This is the frequency the receiver is tuned to. Depending on the LO frequency settings made on the Setup page, the frequency value either shows the true RF frequency received by the antenna or the L-band frequency at the receiver's input. |
| Polarization | If on the Setup page the 'LNB voltage' parameter is set to 'AUTO', the receive polarization as set with the LNB Voltage is shown here. The polarization is shown with the alias names defined at the Setup page unless these are at their default value (H,V). |
| Frequency tracking offset | This value shows the actual frequency tracking offset, the receiver applies to the receive frequency. The true receive frequency used by the receiver is the nominal frequency from the field above with the offset from this field added. A frequency offset displayed here is added to the nominal frequency even if the frequency tracking is switched off. Setting a new nominal frequency value resets the offset to zero. |
| Frequency tracking | Shows if the frequency tracking function is actually enabled. |
| Attenuation | Shows the actual input attenuator setting. |
| Measurement bandwidth | Shows the measurement bandwidth actually used by the receiver. |
| Post detector filter | This is the low pass filter applied to the measured level before the value gets displayed or sent to the analog output of the receiver. The filter corresponds to the video filter of a spectrum analyzer. |
| Noise level | If the receiver operates in one of the C/N measurement modes, this value shows the noise level the receiver measured with the recent measurement. |
| Analog output voltage | This value shows the voltage the receiver actually outputs at it's analog output port. Please note that the reading shown here is not calibrated match the true output voltage exactly. |
| Temperature | The temperature shown is the temperature measured on beacon receiver printed circuit board. The temperature at this place normally is about 20C above the environment temperature, hence temperature readings at 65C are not unusual. |
| Receive Level Alarm | If the receive level falls below the 'Alarm threshold' set on the Settings page, the receiver states FAULT here. |
| Frequency Tracking Alarm | If the frequency tracking function is enabled and the tracking algorithm fails to optimize the receive frequency setting, the receiver reports a FAULT here. |
| Synthesizer Lock Alarm | If one of the PLL synthesizers in the receiver does not lock, a FAULT is reported here. This happens if you tune the frequency out of it's valid range. |
| D/C Supply Alarm | The receiver monitors it's internal supply voltages. if one of them is out of range, a FAULT is stated here. |
