L-band combiners contains an extra active L-band input module (NTC/3497/AA), offering 4 switchable inputs per module (max. 2 per chassis). Each input is also having its amplifier /attenuator in order to equalize the different input signals.
Basically, the unit has 2 major applications:
1 Combining and switching of up to 8 L-band signals,
2 and b) frequency conversion to or from any RF frequency as one of the many options offered.
Other functionalities, such as active L-band splitters, IF/L-band frequency converters, driver units for outdoor frequency converters, etc. are all additional options available within the Azimuth modular system.
If used with frequency converters, the unit will necessarily be equipped with a 10 MHz reference input/output.
All Control and Monitoring parameters are available locally on the front panel (LCD display & keyboard) and remotely through a web interface (Http) or through the RS-485/232 port or through the 10/100 Base-T Ethernet port.
The last two use the RMCPv2 protocol. There is optionally an SNMP + MIB agent.
Satellite uplinks using different L-band carriers, and to be combined over one cable to e.g. a frequency converter.
This unit can also be used as a switching device for e.g. routing purposes or redundancy switching operations.
This is made possible by remote control of each input over the serial bus or the Ethernet bus. RF Frequency block converters can be either built-in, or configured as an outdoor version. (i.e. C-band, Ku-band, DBS-band. etc.)
