Test System Supports Gen5 PCIe

Keysight Technologies offers a comprehensive transmitter (Tx) and receiver (Rx) testing solution providing the speed and margins needed to meet the Peripheral Component Interconnect Express (PCIe) 5.0 Technology (PCIe Gen5) standard. According to the company, PCI Express 5.0 technology is required for computer servers to support the bandwidth of 400G networks, as it is the only significant input/output (I/O) interconnect that has the throughput necessary to support the 400G interface.

 

The Keysight PCIe 5.0 receiver test solution enables the design and validation of circuits capable of tolerating significantly attenuated signals at 32 GT/s.  PCIe 5.0 utilizes aggressive equalization techniques helping the receiver restore the quality of the transmitted signal, allowing for error-free recovery of the digital information from the PCIe Tx signal.  Due to these high data transfer rates, PCIe 5.0 receivers must accept a heavily degraded signal resulting from the channel's high-frequency loss characteristics, resulting in unacceptable bit error ratios (BERs).  To address this, Keysight has developed the M8040A High Performance 64Gbaud BERT, enabling physical layer characterization and compliance testing, to characterize receiver performance margins on the physical layer.
