LeCroy introduces signal integrity network analyzer

The LeCroy SPARQ is a new class of instrument classified as a "signal integrity network analyzer." SPARQ, which stands for "S-parameters Quick," is a TDR/TDT-based analyzer that measures 40GHz, 4port S-parameters with a single button press, at a fraction of the cost of a VNA. Fully calibrated measurements can be made in minutes, and without any need to connect or disconnect cables to calibration kit standards or electronic calibration modules.

SPARQ signal integrity network analyzers connect directly to the device-under-test and to PC-based software through a single USB connection for quick, multiport S-parameter measurements. SPARQ characterizes multiport devices common in signal integrity applications at a fraction of the cost of traditional methods.

It is ideal for developing measurement-based simulation models, design validation, compliance testing, high performance TDR, PCB testing, and portable measurement requirements.

SPARQ is small and weighs less than 20lbs. It connects to any standard PC through a USB 2.0 interface, allowing it to run where computing power is easily upgraded.

The product provides calibrated measurements with a single connection to the device-under-test and offers simple setup choices. Calibration standards are also built into SPARQ. This enables measurements to be made without multiple connection steps and removes the need for additional electronic calibration (ECAL) modules.

SPARQ includes all of the hardware and software tools standard to make signal-integrity measurements. These tools include mixed-mode S-parameter conversion and port-renumbering, passivity, reciprocity and causality enforcement, and built-in time-domain views like impedance, rho, step response and impulse response. All time-domain results can be normalized to the system rise time.

SPARQ can perform all tests currently made with TDR or VNA instruments. Some measurements and tests SPARQ performs include impedance, return loss, impedance imbalance, insertion loss and crosstalk (near- and far-end).
