LNB Current Graph

This graph displays the LNB current only if an LNB is connected to the system and is drawing

current from the LNB current source.

Amplifier Status Graph

This graph displays the state of the RF amplifier (On/Off). Note that, as shown in the example,

On is represented by a 1 (one); Off is represented by a 0 (zero); if no data is available, then a -1

(negative one) is displayed.
