monitors and
controls numerous parameters and has features which simplify installation and use and
enhance system performance.
Some of these key features include:
• Monitor and Control
The IBUC can be monitored and controlled through a couple of interfaces
including RS232 and Ethernet port. See Chapter 5, Monitor and Control Features ,
for a full description of these functions.
• Tx Attenuation
The gain of the unit can be set over a 30 dB range in 0.1 dB steps.
• Automatic Gain Control (AGC)
The IBUC continuously monitors input and output levels. When AGC is enabled,
the gain of the system is maintained at a constant level by an internal algorithm.
Gain is the difference between output power and input power.
• Automatic Level Control (ALC)
Similar to the AGC system, when ALC is enabled, the gain is adjusted to maintain
a constant output level.
• Input Power Overdrive Protection
Based on internal selectable stable references, transistor overdrive will be
measured and automatically assessed. Terrasat’s Inc. algorithm allows the input
overdrive point to be up to 6dB higher than the selected reference point. If such
condition is not met, internal attenuators will be activated to limit power delivery.
• Embedded Web Pages (HTTPS)
• Simple Network Management Protocol (SNMPv3)
Provides integration of IP M&C in existing network management systems.
• Burst Operation
Enables operation in burst mode. The IBUC reports peak output power of valid
bursts (above a burst threshold) when in burst mode.
• Event History (with time stamps)
A log of events that occur is maintained. This can simplify troubleshooting of the
system (especially when an intermittent problem occurs).
• Sensors
A series of internal sensors enable you to verify performance and to troubleshoot
the system. Sensors include internal temperature, 10 MHz input detector, supply
