LeCroy Corp. introduces its SPARQ series of signal integrity network analyzers, which are offered at lower prices than vector network analyzers. The devices in the series are said to measure 40GHz S-parameters on up to 4-ports with single-button press operation.

LeCroy explains that the SPARQ is a time domain instrument that utilizes TDR/T technology and patented technology to rapidly acquire waveforms and measure the S-parameters of a device. Both frequency and time domain results are measured and standard Touchstone S-parameter files are outputted for loading into a simulation software. The compact device is PC-based and portable and comes with all of the hardware and software tools required by the signal integrity engineer for characterizing passive devices. An OSLT calibration kit is installed in the unit and ready to be used with a button click.

The SPARQ series has three models: the SPARQ-4004E (40GHz, 4-port, internal calibration), SPARQ-4002E (40GHz, 2-port, internal calibration) and SPARQ-4002M (40GHz, 2-port, manual calibration).

The "E" model comes with the internal calibration capability standard and also supports manual calibration using an external kit. S-parameter measurements are found in a single setup screen, making setup fast and easy.

Like the software in LeCroy's Windows-based oscilloscopes, the SPARQ has the same overall look and feel and user-friendly operation. It can display up to 16 S-parameters result waveforms simultaneously and allows the user to zoom, reposition and perform math and measurements on waveforms.
