Anritsu MU195040A – SI Error Detection Module, 21G/32G bit/s

The Anritsu MU195040A is a Signal Integrity Error Detection Module that operates from 2.4 to 32.1 Gbit/s and functions as a plug-in unit for the MP1900A Signal Quality Analyzer-R. It delivers bit error rate measurements under stressed signal conditions, including closed-eye scenarios caused by transmission path losses, through a built-in multi-band Continuous Time Linear Equalization (CTLE) function. The module accepts single-ended data inputs from 0.05 to 1.0 Vp-p and achieves typical input sensitivity of 25 mVp-p, enabling near-live BER performance evaluation of transceivers and Device Under Test comparison. With random jitter intrinsic to the module of 115 fs rms (typical), the MU195040A supports both NRZ and PAM4 modulation formats and accommodates dual-channel 32 Gbit/s data input via option x20 for 64 Gbit/s serial communication evaluation.
