Welcome

Welcome to the PCIe4.0 (CEM) TekRxTest application. PCI Express Architecture PHY Test Specification Revision 5.0 and Version1.0.

Figure 1: TekRxTest - PCIe4.0 CEM application

Receiver testing is accomplished by connecting the output of BERT PPG (which can produce specific PCIe test patterns) to the input of the DUT through a specialized set of fixtures and cables. The BERT can be programmed to add different amounts of random jitter, sinusoidal jitter, differential, Common mode interference along with variable signal amplitude, preshoot, and de-emphasis. Output of the DUT is connected to the BERT error detector to identify bit errors on the DUT Tx traffic, either during loopback or during sweep of one of the stress parameters. Any error detected can be assumed to be generated from the DUT Tx path as a result of either the DUT experiencing a bad bit-decision at its receiver or uncompensated back channel loss at the error detector of the BERT. Additionally, DUT Tx traffic can be analyzed to verify the DUT responses to various requests put forward by the BERT during link training process.

Key features and benefits

• Automated Calibration, Link Training, and Compliance Testing.

• Receiver JTOL test for AIC / System DUT.

• Jointly with Anritsu BERT MP1900A series, the receiver solution provides the tools and flexibility required to visualize and control the impairments, observe real-time eye performance for PCIe Gen4 devices.

• Reliable and accurate results reduce the test execution time and minimize the skill-set required to perform calibration and testing.

The PCIe4.0 (CEM) TekRxTest application calibrates the following at TP1 :

1. Amplitude - The differential voltage swing is required to be within 720 - 800 mV. This is done only after the transition and non-transition bit levels are made equal using de-emphasis.

2. Tx Equalization Presets - The various levels of de-emphasis and preshoot are required to be calibrated within the tolerance as specified.

3. RJ - It is calibrated to be 1 ps (RMS value).

4. SJ - The SJ is calibrated over the desired range of 5-10 ps (pk-pk) including the nominal SJ specification of 0.1 UI (6.25 ps) at 100

MHz frequency).

5. SJ @ 210 MHz - If the stressed eye calibration requires sinusoidal jitter levels greater than 0.1 UI, then SJ@210 MHz is used during JTOL test.

6. Multi-tone - It is calibrated over a specific range for multiple user-defined frequencies.

You must perform TP1 calibration before you start performing the calibration for TP2.

The PCIe4.0 (CEM) TekRx test application calibrates the following at TP2:

1. DMI - The differential mode sinusoidal interference is required to be calibrated within 10 - 25 mV (pk-pk) by capturing the 2.1 GHz sinusoidal output for a duration of at least 125 us.

2. CMI - The common-mode sinusoidal interference is required to be calibrated for a nominal voltage of 150 mV (pk-pk) by capturing the 120 MHz sinusoidal output for a duration of at least 125 us.

Operating basics

meets the stressed eye targets.

loss measurements and report the mean insertion loss. This way, any error in a particular acquisition will get averaged out. The mean of scope noise is usually zero. If we have a large number of samples and we average out those samples, then the noise component in the averaged sample will be zero.

# avgs The number of averages that will run the insertion loss measurement multiple times

and calculate the average value. This way, any error in a particular acquisition will get averaged out.
