Abstract

This paper describe a bit error rate test equipment. It was developed as tool for testing an high speed modem for digital radio communications. It uses two programmable logic devices PAL 22V10 (GAL are good replacements) and some common 74HCxx IC. The modem interface (data and clock) meets standard EIA RS422 but can be easily replaced. BERTE includes a programmable clock generator and accept also an external clock. It generates some useful bit sequences: all zero, all one, alternating one and zero (square wave), programmable pseudo-random bit sequence (up to 2exp24-1 bit length). Pressing a push button it's possible to insert an error bit into the sequence. The error counter is external.
