 ■  Function Introduction

1.Diverse signal generation capabilities

• NRZ and PAM4 signals, such as PRBS7, PRBS9, PRBS11, PRBS13, PRBS13Q, SSPRQ, etc.

• Single tone signal;

• Noise signal with customizable bandwidth;

• NT signal, such as 1T, 2T, …, 5T, etc.;

• Clock signal;

• Timing jitter injection, supporting Sj (sinusoidal jitter) and Rj (random jitter);

• Error injection, supports injecting error bits into PRBS patterns by percentage or error position;

• Noise injection, which is achieved through noise signal generation and combining;

• Sinusoidal interference injection, which is achieved through the generation and combination of sinusoidal signals;

• SSC, supports setting parameters such as modulation depth and modulation frequency;

• Duty cycle deviation supports duty cycle deviation of clock signal;

• Rate deviation, supports adjusting the signal rate with an accuracy of 0.1%;

• Channel embedding, supporting the application of channel response in the form of S parameters (single-ended or differential);

• FFE, supports user-specified transmitter equalization coefficients;

• Transmitter pre-distortion, which can achieve better signal quality

Luna-Suite High-Speed Serial Interface Test Software Suite

        MET's MWG-242 series arbitrary waveform generator (AWG) uses the test suite Luna-Suite to complete the functions detailed in this section, and also supports users to configure the product in a programmable manner. Luna-Suite's software is powerful and simple to operate, which reduces the threshold and time for operators to use this type of high-speed arbitrary waveform generator.

02  Typical use cases

Send "PRBS7@6Gbps，400mVp-p" High-speed serial signal

1.The MWG-242A is used to generate a 6 Gbps PRBS7 high-speed serial signal with a waveform amplitude of 400 mVp-p. The transmitter sets the above parameters and sends the waveform. The receiver of this use case is completed by MET's MDO-401A series high-speed oscilloscope (for details, please refer to this series of articles).

2.In the top menu bar of the Luna-Suite operation interface, click the "De-Enbed" button to configure the test item related parameters. After the configuration is completed, click the "Update" button on the right to complete the upload settings.

03  Other selection references

        MET Technology's MWG series arbitrary waveform generators offer a variety of sampling rate/bandwidth options.

        If you need a higher rate, you can choose the MWG-242 series or MWG-202 series. They have larger bandwidth and higher sampling rate, and can be widely used in the fields of autonomous driving (ADAS, domain controller, SerDes testing), AI computing (MIPI, DDR testing), high-speed interconnection (PCIe, USB, Ethernet testing) and signal integrity (High-Speed cable, backplane testing) and other scenarios.

        If a lower rate can meet your test needs, you can choose the MWG-122 series or MWG-102 series. They are equipped with 12 GSa/s and 10 GSa/s sampling rates respectively, with better cost performance. On the MET Luna-Suite platform, you can achieve powerful high-speed serial signal generation and analysis functions.
