Method for testing communications channels

摘要

A method for testing communication channels of a satellite using a 16-bit run-length compression algorithm wherein the most significant bit (MSB) is used to represent the errored or not errored condition of the compression algorithm. Error patterns are read and downloaded into a PC interface card which decompresses the file real time and passes the error pattern to a bit error rate summer board. The bit rate summer board overlays the error pattern onto the communication links of the satellite which causes precise bits to be errored accordingly.
