The 70MHz to L-Band Quad Up-Converter consists of a single 19" wide, 1 RU shelf assembly. The unit contains four Up-converters
from 70 MHz to L-band, power supply, reference oscillator, monitoring and control to manage the up-converters.
The up-converters receives four IF 70MHz (140 MHz optional) signals from four classic modulators or some indoor units
and converts them to four L-Band signals with different RF frequencies for multi-transponder operation. 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
