3.3.6 Calibration Menu
When the controller is set up to perform LNA/LNB Fault Tracking, the LNA or LNB nomi-
nal current should be calibrated from the controller. First, set the controller for LNA/LNB
Fault Tracking by performing the following process:
Press the Main Menu key; select 4.Flt. Setup and press the Enter key; select 1.Mjr.
Faults and press the Enter key; select 1.LNA/LNB and press the Enter key. See
Section 3.3.4 and Figure 3-8. The following menu selections allow for calibration of the
LNA/LNBs. See Figure 3-10.
3.3.6.1 Flt. Window
Allows the user to select the sensitivity of the alarm detection. Select from four window
settings (8%, 12%, 15% or 20%) which are a percentage of the total current being
consumed by the LNA/LNB. The 8% setting is the most sensitive and 20% is the least
sensitive. The factory default setting is 8%.
3.3.6.2 LNA/LNB PS
Selects between three output voltage ranges for LNA/LNB power supplies: 13V, 17V or
26V (available on RCP2-HP models only) output. Maximum output current at the 13/17V
range is 900 mA; and is 1500 mA for 26V output. This option can be used to switch
between bands of dual band LNB units or to connect higher power converters. All three
channels will switch output voltage simultaneously. For a detailed description of LNB/
LNA power supplies, refer to Section 5.0.1.
