Double D Electronics DDA291
The DDA291 is an RF level measurement subsystem, primarily intended for measuring satellite beacon levels. It includes an internal beacon receiver, which is used for signal level measurements. The unit has four inputs (channels) for connection to LNBs. One input at a time can be selected to drive the beacon receiver. The unit includes power supplies for the LNBs, and also bias tees to inject power onto the RF inputs. All four supplies are continuously active, regardless of which input is being used.
This connector communicates with the device using a serial connection.
