Anritsu MP1800A BERT repair

The Anritsu MP1800A is a modular BERT (bit error rate tester) mainframe used for high-speed digital transmission testing in 10G, 25G, and 40G/100G Ethernet, OTN, and serial data standards work. It’s used in semiconductor characterization labs, optical transceiver manufacturing, and network equipment development. The modular architecture means the mainframe and individual signal generator or error detector modules can fail independently. Anritsu still sells current BERTs, but older MP1800A configurations are past their support window.

The most common issues we see: signal generator output amplitude degradation (reduced eye opening, signal-to-noise problems on the DUT), clock recovery module failures that cause synchronization errors, and error detector sensitivity loss that produces false bit errors. The mainframe’s GPIB or LAN communication can fail on units that have been in automated test racks for many years. Individual modules can also develop internal clock jitter issues from component aging.

We test each module type against its specification - signal generator output levels and jitter, error detector sensitivity, clock recovery performance, and mainframe communication. Module-level repair, output calibration, and NIST-traceable timing/amplitude verification close the service. We test on both the mainframe and at the module connector level.
