The MP1630B is a general purpose Bit Error Rate measuring instrument that can simultaneously measure up to 16 channel signals and burst signals in the range from 10 kHz to 200 MHz. The built in high performance synthesizer generates high accuracy signals across a wide frequency range up to 200 MHz. A variety of test patterns can be generated which includes PRBS, Programmable, Zero Substitution, Mixed and PON pattern. With the Mixed Pattern, test signals such as SONET/ATM pseudo test signal including complex communications protocols can be generated.
