Engineered to Endure
When you set up your system and the Tx Output reaches its budgeted level, Terrasat
recommends that, instead of the (P1dB - 20 dB) to (P1dB + 1 dB) threshold range
that is the default, you narrow the range between the high and low thresholds to
±3 dB.
Example
: After observing the unit, you determine that the output level operates
consistently at 32 dBm. Although the threshold range is 21 dB, that range is too
wide for everyday use. Instead consider setting the output thresholds at ±3 dB; this
would make the high level threshold 35 dBm and the low level threshold 29 dBm.
If the IBUC unit is configured for burst power monitoring, command
the burst threshold value. See
4. Verify your settings.
Configuring Alarm States
The IBUC offers flexibility with the levels of alarms produced when user

specified
thresholds are exceeded.

alarm configuration. Each alarm that is user configurable can be set as a major
event, a minor event, or be disabled.

Configuring ALC/AGC
The Cyber Hardened IBUC

and IBUC

offer two
methods of ensuring consistent signal levels: automatic level control (ALC) and
automatic gain control (AGC).
ALC
When enabled, the Automatic Level Control (ALC) circuitry in the IBUC monitors
output levels and adjusts the gain to maintain a consistent output for input signal
variations. If a signal level is consistently below the predetermined target level, the
ALC will cause the gain to be increased until the target level is reached. If a signal
level exceeds the target level, the ALC will decrease the gain.
