Part #: XBER-4

X-COM Systems, The XBER-4 Naval Tactical Data System (NTDS) Type E Serial Switch Bit-Error Rate Tester (BERT) tests the quality of transparent switch channels.

As part of X-COM's line of Commercial-Off-The-Shelf (COTS) NTDS solutions, the rackmountable XBER-4 can significantly reduce maintenance time and effort. The XBER-4 enables the user to troubleshoot and quickly identify switch channels that do not meet minimum BER requirements. It is designed to cost-effectively meet the unique needs of today's NTDS development, evaluation, and training environments.

Applications
Specifications

Applications

The XBER-4 is typically used to verify the integrity and quality of communication links that are routed through transparent active and passive switch channels. When connected to any two channels of an active or passive LLS switch, the XBER-4 generates and transmits pseudo randomly-generated packets. The data returned is then compared to directly measure the bit-error rate. The XBER-4 provides a means for technicians to directly measure the quality of NTDS switch channels and significantly reduces system troubleshooting time and effort.
