Welcome
Welcome
Welcome to the PCIe4.0 (Base) TekRxTest application. This application performs the test as per the Gen 4 Base specification Revision 5.0
Version 1.0
Figure 1: TekRxTest - PCIe4.0 Base 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.
Key features and benefits
•PCIe Gen4 Receiver JTOL Testing as per Base specification for Non-Root complex / Root Complex devices.
•Automated calibration, forced loopback initiation, and testing.
•Jointly with Anritsu BERT MP1900A series, the receiver solution provides the tools and flexibility needed to visualize and control
impairments , observe real-time eye performance, etc. for PCIe Gen4 devices.
•Reliable and accurate results reduce the test execution time and minimize the skill-set required to perform calibration and testing.

TP1 Calibration
The TP1 calibration panel allows you to perform calibration for TP1 and save the results. You can perform calibration for Signal Amplitude,
Preset, Random Jitter (RJ), Sinusoidal Jitter (SJ), SJ@210 MHz, and Multi-tone. Additionally, there is a provision to perform AC-DC
Balancing.
The PCIe4.0 (Base) 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.

sinusoidal output for a duration of at least 125 us.
