The Anritsu MP1900A Signal Quality Analyzer-R is a high-performance bit error rate tester (BERT) built on an 8-slot modular mainframe designed for physical-layer evaluation of next-generation high-speed digital interfaces. The platform supports a wide range of plug-in modules covering pattern generation, error detection, jitter modulation, and noise injection, allowing a single instrument to address both NRZ and PAM4 signaling across multiple lanes and protocols.

Anritsu identifies the MP1900A as a solution for early-stage R&D evaluation of high-speed serial interfaces including 200G and 400G Ethernet, PCIe Gen3 through Gen5, USB 3.1 Gen1 and Gen2, Fibre Channel, InfiniBand, and CEI 56G and 112G applications. The instrument is positioned for engineering teams characterizing transmitter quality, receiver jitter tolerance, link training behavior, and bit error rate compliance against standards published by IEEE, OIF-CEI, PCI-SIG, and the USB-IF.

ValueTronics International, LLC has been serving test and measurement professionals since 1992 from our 20,000 sq ft secure warehouse at 1675 Cambridge Drive, Elgin, Illinois. Unlike drop-shippers or pass-through brokers, every instrument we sell is physically held, inspected, and tested by our in-house team before it ships. This includes complex modular platforms like the MP1900A, where configuration verification, module compatibility checks, and physical condition assessment require hands-on engineering knowledge rather than catalog lookups. When you order from ValueTronics, you are working with a company that has the instrument in its own facility and can answer specific questions about the specific unit you will receive.

Brand Heritage

Anritsu Corporation is a Japanese test and measurement company with roots tracing back to 1895, making it one of the oldest continuously operating instrument manufacturers in the industry. Anritsu acquired Wiltron Company in 1990, integrating Wiltron's RF and microwave measurement expertise into the broader Anritsu portfolio, and has maintained its independent corporate identity through subsequent decades of growth in wireless, optical, and high-speed digital test markets.

Compare Other Models in This Series

The MP1900A platform is configured through module selection rather than through model variants. A complete BERT system consists of the MP1900A mainframe plus one or more pattern generator modules, error detector modules, and supporting jitter and noise modules. The combinations selected determine whether the system addresses NRZ-only applications below 32.1 Gbit/s, PAM4 applications up to 64.2 Gbaud, or multi-channel synchronized configurations for high-lane-count standards.

Anritsu organizes the module ecosystem around generation (PPG modules), analysis (ED modules), stimulus impairment (jitter modulation, noise generation), and clock distribution (synthesizer). A single mainframe can accept up to eight modules, and combination functions allow multi-channel synchronization for emulating standards such as 400G and 800G Ethernet that require multiple correlated lanes.

Each MP1900A configuration linked below is its own product page on valuetronics.com with pre-owned-matched pricing reflecting that specific unit's installed module set, option strings, and inspection status. Because the MP1900A is a modular platform, the value and capability of a specific unit depends heavily on which modules and options are installed.

This MP1900A listing represents a specific mainframe and module configuration. Confirm the installed module model numbers and option codes against your application requirements—particularly for PAM4 baud rate options, equalizer options, clock recovery options, and software licenses such as MX183000A jitter tolerance or PCIe link training.

Pattern generator module differences are driven by signaling format and baud rate. The MU195020A 21G/32G SI PPG covers NRZ generation through 32 Gbit/s with optional 10-tap emphasis and variable ISI. The MU196020A PAM4 PPG covers PAM4 and NRZ generation through 32, 58, or 64 Gbaud depending on installed option (001, 002/112, or 003/113/123), with 4-tap emphasis, adjustable ISI, and optional FEC pattern generation. Error detector differences follow a parallel logic: the MU195040A SI ED handles NRZ through 32 Gbit/s with optional CTLE and clock recovery, while the MU196040A and MU196040B PAM4 EDs add PAM4 analysis with built-in DFE, Low Frequency Equalizer, and broader clock recovery coverage extending to 58.2 Gbaud on the MU196040B.

Supporting modules complete the picture. The MU181000B 12.5 GHz 4-port Synthesizer provides clock distribution with optional internal jitter modulation and SSC. The MU181500B Jitter Modulation Source adds independent SJ1, SJ2, RJ, BUJ, and SSC for compliance-grade jitter tolerance testing. The MU195050A Noise Generator provides DMI, CMI, and white noise for PCIe and TBT3 receiver stress testing.
