The WaveMaster 8000HD series from Teledyne LeCroy goes where no 12-bit oscilloscope has gone before. Serial digital data streams never stop reaching for higher data rates. Buses such as PCIe Gen 6 (64 Gtransfers/sec) and USB4 V2 (80 Gb/sec) have gone to PAM4 and PAM3 modulation, respectively, to reach their current data rates. Two-level modulation […]

What is jitter and what can I do about it (part 2 of 2)?
Operations on acquired jitter data help quantify jitter values. Part 1 of this article described the oscilloscope eye diagram and unit interval (UI) and focused on a single ideal rising edge with 28 additional edges representing some degree of jitter (Figure 1). We determined the peak-to-peak jitter to be 15 ps, based on the edges […]
What is jitter and what can I do about it (part 1 of 2)?
Measuring and quantifying jitter are the first steps toward controlling it. Jitter is a measure of the timing performance of a digital data stream such as Ethernet, USB, PCIe, or HDMI. It defines when data transitions occur in relation to an ideal waveform. Excess jitter can lead to signal-integrity problems that result in high bit-error […]
Measurements verify power integrity
Engineers should measure and analyze power integrity on the power and ground planes of a board’s power distribution network. Understanding power integrity is crucial when evaluating circuit power quality because it has a direct influence on performance. Power integrity is a subset of signal integrity, whose assessment ensures that signals have suitable amplitude, rise time, […]
Protocol test system handles USB Power Delivery, USB Type-C, USB 3.2 link layer compliance testing
The Voyager M4x Analyzer/Exerciser system has been approved by the USB Implementer’s Forum (USB-IF) for USB Power Delivery (USB PD), USB Type-C Functional and USB 3.2 Link Layer compliance testing. The Voyager M4x also supports USB4 logical and protocol layer compliance allowing this single test platform to address the most critical technologies within the USB […]
PCI Express 5.0 interposer works with protocol analyzers
A PCI Express 5.0 Mini Cool Edge IO (MCIO) interposer works in combination with Teledyne LeCroy’s Summit family of PCI Express 5.0 protocol analyzers. The new interposer enables engineers to test products that incorporate card edge connectors or cabled connector assemblies that utilize the MCIO mechanical connector with PCIe 5.0, NVM Express (NVMe) or Compute […]
USB Type-C test coupon fixtures speed scope debug tasks
New USB Type-C High-speed and Sideband Test Coupon Fixtures provide the industry’s first oscilloscope solution for high-speed probing and analysis of an active data link at the USB Type-C connector. Additional connection to a Teledyne LeCroy protocol analyzer provides complete debug capability of any USB Type-C link negotiation failure. USB Type-C devices undergo negotiation when […]
RF test system handles Bluetooth Basic Rate, Extended Data Rate, LE technologies
The FRVS RF test system has been approved by the Bluetooth Special Interest Group (Bluetooth SIG), the governing body for Bluetooth technology, for testing Bluetooth Basic Rate (BR), Extended Data Rate (EDR) and Low Energy (LE) technologies. It is estimated by ABI Research and the Bluetooth SIG that about 4.5 billion Bluetooth enabled devices were […]
Analyzer performs USB4 compliance tests
A USB4 compliance test option for the Voyager M4x analyzer and exerciser system can be used in conjunction with the USB Implementers Forum’s (USB-IF’s) USB4 Command Verifier (USB4-CV) software to generate traffic conditions and verify responses for the official USB4 logical, protocol, and tunneling layer compliance test specifications. USB4 combines the simplicity of the USB […]
