The SatDbTcAttenuation data record contains the attenuation values stored in the database for one particular pair of antennaId and tcId. This is the attenuation to be applied for the given TC signal when transmitted by this antenna. The two attenuation values are applied to the same signal at different stages of the transmit chain, e.g. at the upconverter and the HPA.
Data Model
| Key | Type | Value |
|---|---|---|
| attenuationId | Number | unique, primary key, auto generated |
| tcId | Number | ID of the TC signal this data record belongs to |
| antennaId | Number | ID of the antenna this beacon belongs to |
| attenuation1 | Number | transmit attenuation1, floating point, dB |
| attenuation2 | Number | transmit attenuation2, floating point, dB |
| modified | String | timestamp, generated by database at creation / modification time |
