Abstract
We present a simple, all electrical method for the generation of test signals for testing of fiber-optic coherent CPFSK IF receiver systems, using a programmable bit error rate tester. The feature to be able to add phase noise to the IF signal makes it possible to evaluate receiver system behavior with relation to local oscillator phase noise.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
