The 70MHz to C-Band Up-Converter consists of a single 19" wide, 1 RU shelf assembly. The unit contains one Up-converter from 70 MHz to C-Band, power supply, reference oscillator, monitoring and control to manage the converter. Optionally, the unit also could have two up-converters from 70 MHz to C-Band and two power suppliers to be configured as 1:1 built-in redundant operation.
The up-converter receives one IF 70MHz (140 MHz optional) signal from classic modulators or some indoor units and converts them to a C-Band signal for one C-Band input SSPA. All necessary power and reference signals are provided by internal sources.
The enclosure is a compact 1 RU shelf of light but robust construction which houses the power supply, monitor and control and reference source.
The built-in monitoring and control subsystem allows readings of critical parameters and alarm signals to be retrieved from the up-converters. These may be used to activate front panel indicators or to be sent through a serial interface for remote control. An internal reference signal (10 MHz) is built into the unit to lock the PLL oscillators of the up converters.
The front panel has an alphanumeric display, with LED indicators and 6 pushbuttons for interrogation, command and control operations. Control over the up-converters may be exercised from the front panel or extended remotely to a PC via the serial interface plug at the back of the shelf.
With the Advantech's 1: N (up to 12 now) switching controller, up-converters can easily be configured for 1: N redundant operation
