Core Viewpoint - The rapid rise of AI technology has led to an exponential increase in the demand for data bus throughput in servers and computing devices, necessitating upgrades in PCIe standards to meet these requirements [1][2]. Group 1: PCIe Standards and Challenges - PCIe standards have evolved to PCIe 6.0 and 7.0, achieving signal frequencies of up to 128 GT/s and expanding channel configurations from x1 to x16 to facilitate high bandwidth transmission [1][2]. - Higher signal frequencies result in exponential increases in insertion loss, leading to reduced signal amplitude and distortion, while impedance discontinuities in PCB traces can cause signal reflection and timing jitter, impacting signal integrity [1][2]. Group 2: Insertion Loss and Impedance - Insertion loss refers to the power loss due to conductor and dielectric losses as signals pass through PCB transmission lines, typically measured in decibels (dB), with PCIe 5.0 requiring insertion loss not to exceed 0.6 dB at 16 GHz [3]. - Characteristic impedance, determined by the geometric structure and material properties of transmission lines, is typically recommended at 50Ω or 100Ω (differential), with impedance mismatches leading to signal reflection and return loss degradation [5]. Group 3: Testing Methods - Vector Network Analyzers (VNAs) are the preferred instruments for measuring insertion loss, allowing direct comparison of output and input signals to reflect losses [9][11]. - The Delta-L method, developed by Intel, enhances measurement accuracy by compensating for fixture effects and impedance mismatches, making it a mainstream method for PCB production testing [12][18]. Group 4: Rohde & Schwarz Testing Solutions - Rohde & Schwarz offers a comprehensive range of vector network analyzers, including models like R&S®ZNA, R&S®ZNB, and R&S®ZNBT, covering frequency ranges from 9 kHz to 110 GHz, catering to diverse testing needs [20]. - The integrated Delta-L functionality in Rohde & Schwarz VNAs allows for efficient insertion loss testing without external computers, streamlining the testing process [21][22]. - The TDR functionality in Rohde & Schwarz VNAs supports various window functions and time-domain enhancement algorithms, displaying both impedance and frequency domain S-parameter information for effective diagnostics [27][29]. Group 5: Future Outlook - Rohde & Schwarz's ZNA/ZNB/ZNL series, equipped with electronic calibration components and built-in impedance testing capabilities, redefine PCB insertion loss and impedance testing standards, addressing the higher demands of future 6G communications and AI server applications [35].

Core Viewpoint - The rapid development of PCIe 6.0 and upcoming PCIe 7.0 technologies is leading to significant increases in transmission rates, from 112 Gbps to 224 Gbps, with future applications potentially reaching 448 Gbps. This increase in speed brings challenges related to signal integrity (SI), making TDR (Time Domain Reflectometry) testing a crucial tool for engineers to address these issues [1][26]. Group 1: TDR Testing and Signal Integrity - TDR testing is essential for measuring transmission line impedance and identifying signal path issues, providing engineers with a key method to tackle high-speed signal integrity challenges [1][26]. - Traditional TDR testing methods involve using step signal sources and oscilloscopes, while modern approaches increasingly utilize vector network analyzers for TDR measurements [2][26]. - Observations during TDR testing show that impedance curves tend to increase over time, with a notable rise of approximately 7 ohms from 0.11 ns to 3.45 ns, regardless of whether single-ended or differential testing is conducted [2][23]. Group 2: Impedance Rise Phenomenon - The phenomenon of impedance rise is attributed to transmission line losses, primarily caused by conductor resistance, which increases the slope of the impedance rise [26]. - The RLGC model is used to describe transmission line characteristics, where R represents series resistance, L represents series inductance, G represents parallel conductance, and C represents parallel capacitance [6][10]. - The characteristic impedance of a transmission line can be derived from the telegrapher's equations, indicating that TDR measurements reflect this characteristic impedance [7][8]. Group 3: Practical Measurements and Results - Measurements on a PCB differential line showed a DC resistance of approximately 2.4 ohms for the signal line and 0.3 ohms for the ground, totaling 2.7 ohms, with a differential resistance of 5.4 ohms [18][23]. - The TDR testing results indicated a rise of 3.6 ohms and 3.3 ohms for single-ended impedance, and 7.1 and 7.2 ohms for differential impedance, which aligns closely with the calculated DC resistance values [23][26]. - Standards such as those from the Open Alliance provide guidelines for correcting TDR impedance results, emphasizing the importance of addressing the impedance rise phenomenon in practical applications [23][25].
