The M8040A is a 64 GBaud high - performance Bit Error Rate Tester (BERT) launched by Keysight. It is mainly used for physical layer characterization and compliance testing. It supports PAM4 and NRZ signals and can meet the testing requirements of chips, devices, transceiver modules and other related equipment with data rates up to 32 GBaud and 64 GBaud in industries such as servers, computing, data centers and communications.
Features
Wide data rate range: It supports PAM4 signal data rates from 2 to 64 GBaud and NRZ signals, covering the testing of various high - speed digital interface standards such as PCIe 6.0/5.0/4.0, 400 GbE, etc.
High signal quality: With short transition times and low intrinsic jitter, it can provide pure NRZ and PAM4 signals, ensuring the accuracy and repeatability of test results.
Real - time error detection: It has true real - time PAM4 error detection capability with a data rate of up to 58 GBaud, enabling precise analysis of low bit error rate situations.
Built - in multiple functions: It includes de - emphasis, analyzer equalization and clock recovery functions, which can effectively compensate for signal losses and distortions during transmission.
Rich jitter injection functions: It integrates and calibrates various jitter injections such as RJ, PJ1, PJ2, SJ, BUJ and clock/2 jitter, etc., which can simulate different interference situations and be used to test the performance of devices under various jitter conditions.
Dual pattern generator channels: Each module has two pattern generator channels, which can be used to simulate interference source channels, facilitating the study of crosstalk and interference effects between signals.
Diverse pattern generation methods: Patterns such as PRBS and QPRBS can be generated through algorithms, or patterns stored in the memory can be used, or patterns can be generated through a pattern sequence generator. It also supports PAM4, Gray coding, FEC coding, pre - encoder and error distribution analysis, meeting the pattern requirements of different test scenarios.
Supports multiple standard tests: It can perform receiver (input) tests on many popular interconnection standards, covering a wide range of standards such as Ethernet, Fibre Channel, PCI Express, etc., with a wide application range.
Upgradability: All options and modules can be upgraded, enabling users to expand the functions of the instrument according to future testing needs and protecting users' investment.
Test points close to the device under test: The remote front - end and 1.85 mm short cable design allow the test points to be as close as possible to the device under test, reducing signal attenuation caused by lossy channels and improving test accuracy.
