DM240XR High-Speed Digital Modulator Introduction

MN-DM240XR– Revision 13 1–2

eliminating the need for external Group Delay/Amplitude Equalizers. AutoEQ™ will

automatically generate the proprietary profile for the DM240XR to pre-distort the modulator,

resulting in Amplitude and Group Delay equalization over the Satellite Link. The AutoEQ

will

operate over the full transponder from a symbol rate of 10.1 Msps to 45 Msps.

Additional features include the choice of remotely interfacing through one of three onboard

connections: 10/100 Base-T Ethernet, RS-485, RS-232 or Web Browser. The familiar Radyne

Front Panel (Figure 1-1) offers push-button control of all features and a backlit LCD display.

Menus are specifically designed for ease of use and quick online operation as well as changes in

all modulator configurations.

The DM240XR supports optional 1:1 Redundancy for data, IF or both offering superior system

reliability based on customer needs and applications.

Redundancy Options support include:

• RCS11: 1 RU Chassis that supports redundancy for both IF (70/140MHz or L-band) and

supports various data interfaces.

• RRS11: 1RU Chassis supports redundancy for either 70/140 MHz or L-band. Includes

easy access to monitor ports for online and offline monitoring via the front panel. Power

and control logic is supplied by a rear panel connector on the DM240XR.

• STS11: Small package design that supports redundancy for either 70/140 MHz or L-

band. Includes easy access to monitor ports for online and offline monitoring via the

front panel. Power and control logic is supplied by a rear panel connector on the

DM240XR

• Data Redundancy: The DM240XR PIIC interfaces allows for data redundancy when dual

interfaces are installed. The modulator can satisfy the user's applications when the

system requires monitoring of the redundant data paths. Simply configure the redundant

interface and the modulator will monitor the integrity of the data paths and switch in the

event data is corrupted on either path.
