GENERAL DESCRIPTION The EK-CDP/1 board allows to connect the EK-MFR/1 unit to the SHF parts inserted into the Eurotek Out Door Units (ODU) and allows the use of every frequency band, at present, available. Thanks to the use of two N type connectors every single board can control simultaneously two external sections (ODU) in completely independent way one from the other.

The number of the channels are included between 1 and 256 with a step of 1. >>Enable Rx This menu allows to enable the receiving ODU (out door unit). If the variable “yes” is settled, the ODU is enabled, while if the variable “no” is settled, the ODU is disabled. >>IF BW It is possible to set the receiver IF bandwidth.

The software configuration of the board is realized to obtain the release of the following programmable devices (DSP, FPGA, CPLD, RamDisk). The release version of the FPGA is not available because the device is not present on the board.
