All-in-One Support for Evaluating Next-Generation NRZ/PAM4 Network Interfaces and High-Speed Serial Buses

The Signal Quality Analyzer–R MP1900A is a modular Bit Error Rate Tester (BERT) installing a pulse pattern generator (PPG) for outputting high-quality multi-channel NRZ/PAM4 signals over a wide bandwidth of 2.4 Gbit/s to 32.1 Gbit/s, a high-sensitivity input error detector (ED), Jitter modulation sources for Jitter Tolerance tests, etc.
Additionally, optional noise generation and 10Tap Emphasis functions can be installed for Voltage Noise Tolerance tests, etc., and installing the High-Speed Serial Data Test Software MX183000A software enables efficient design evaluation for increasingly faster PCIe, USB, and Thunderbolt receivers.

Easy Flexibility for Multi-Channel Measurements at Various Transmission Rates and Formats

The MP1900A series is an 8-slot modular instrument that can be easily customized by selecting and adding required function modules. This flexible expandability supporting the latest communications methods ensures both efficient R&D investment and the fastest time to market.

  • 8 slots (per one MP1900A main unit)
  • Maximum transmission capacity up to 512 Gbit/s supporting up to 16ch of NRZ (using 2ch PPG in all 8 slots)
  • All-in-one support for both high-speed network interfaces and bus interfaces such as PCIe

Strengthened Signal Integrity Evaluations in Addition to New SI PPG, SI ED and Noise Generator Modules

The 10Tap Emphasis option installed in the transmission-side 21G/32 Gbit/s SI PPG MU195020A can accurately replay simulated waveforms for various devices and channels (corrected for loss after passage through channel) to help improve design efficiency.

  • Bit rates of 2.4 Gbit/s to 32.1 Gbit/s
  • 10Tap Emphasis
  • Variable ISI function
  • Multi-band CTLE (supports 8, 16, and 28 Gbit/s bands)
  • Low Intrinsic Jitter data output 115 fs rms (typ.)
  • High input sensitivity 15 mV (EYE Height) (typ.)
  • NRZ/PAM4 support
  • CDR SSC support
  • Jitter (SJ/RJ/BUJ/SSC) and noise (CM/DM/White) tolerance measurements

The Variable ISI (option) can generate a signal with simulated Loss between the Tx and Rx channels of high-speed devices and can also easily output a Loss-corrected waveforms. As a result, channel-Loss dependent high-speed device performance tests can be run easily with good reproducibility, helping cut development time.

PCIe Link Training and LTSSM Analysis Function (MX183000A-PL021)

The explosive growth of data traffic due to the worldwide spread of smartphones and mobile terminals is accelerating adoption PCI Express Gen4 (16 GT/s) for communications equipment bus interfaces.
In addition, the faster PCI Express Gen5 (32 GT/s) standard is already being investigated as a means to increase speeds. Key issues are how to shorten design verification times for assuring signal integrity and how to hold-down infrastructure costs.
Interconnectivity between devices and equipment is an important subject in adoption of these high-speed serial interfaces, and troubleshooting whether a Link establishment fault is due to either a physical or logical cause is also important.
The MP1900A series PCI Express function has Protocol Awareness with a normal operation Link Training function for evaluating the PHY layer including Logical Sub-block plus an LTSSM (Link Training Status State Machine) analysis function for detecting abnormal state transitions. These all-in-one functions facilitate efficient PHY layer evaluation of PCIe Gen1 to Gen5 receivers through inspection and fault troubleshooting.
