LNB Current Window
LNB Current Window (%)
Any LNB current reading that is outside the window may generate an alarm, a fault, or may be
masked entirely depending on the state of the user-configured fault mask (see the MSK
command syntax in Chapter 5. SERIAL INTERFACE OPERATION for more information).
For example: If the LNB draws 100mA, and the LNB current fault window is set to the default
value of 30(%), then the allowable current draw for the LNB will be from 70 mA minimum to 130
mA maximum because the window is ±30% centered on the calibrated LNB current draw.
Click [Submit] to save.
Calibrate LNB Current
Calibrate the LNB only when it is running at nominal operating conditions.
The value provided here (in mA) is intended as a reference point. The alarm upper and lower
thresholds are determined by this value and the LNB current window setting.
Click [Calibrate] to perform an LNB calibration and display the updated read-only value.
