TDR and S-Parameters

WavePulser 40iX High-speed Interconnect Analyzer

WavePulser 40iX is the ideal single measurement tool for high-speed hardware designers and test engineers. The combination of S-parameters (frequency domain) and Impedance Profiles (time domain) in a single acquisition with a deep toolbox provides unmatched characterization insight of high-speed interconnects.

Complete frequency characterization with a frequency range from DC to 40 GHz and supporting single-ended and mixed-mode S-parameters. Built-in automatic internal calibration is fast and easy. The OLST calibration kit supplied in the WavePulser-40iX-BUNDLE permits the measurement reference plane to be moved as required.

Impedance Profile

Precisely locate impairments with a spatial resolution of <1 mm and supporting both differential and common-mode impedance profiles. Both TDR and TDT capability are provided for complete coverage of both reflected and transmitted responses.

Deep Toolbox

WavePulser 40iX measurements are ready for simulation for with standard deep toolbox for simulation, de-embedding and time-gating. A built-in eye diagram display also permits equalized emulation. Advanced jitter analysis permits measurement of Total (Tj), Random (Rj) and Deterministic (Dj) jitter with de-convolution of Dj into component parts and a variety of jitter views.

Internal, Automatic Calibration

WavePulser calibration standards are built-in (included in the standard unit) and calibration is always automated, simple and fast - make one connection to the DUT and press Go. WavePulser does not require purchase of additional, external calibration standards. Furthermore, WavePulser's TDR/TDT-based approach is independent of setup, making calibration less likely.

Full-range DC to 40 GHz

WavePulser provides results to DC, and extending to 40 GHz of bandwidth, so TDR step response and time-gated and/or emulated physical layer signal responses can avoid extrapolations for low-frequency and DC response - ideal for interconnection systems. set and usability for high-speed interconnect testing.
