The arrival of 8 and 12-port signal integrity network analysers have been announced by LeCroy Corporation for making S-parameter measurements.
Cloud computing, mobile computing, smartphones and streaming video applications are pushing the marketplace to deliver greater and greater network bandwidth. To meet this need, communication standards utilise multi-lane differential signalling to carry traffic at ever-increasing bitrates.
With the SPARQ-3012E, users can measure the complete 12-port S-parameter matrix in both single-ended and mixed-mode representations.
The resulting S-parameters characterise the near-end (NEXT) and far-end (FEXT) crosstalk between up to three differential lanes, which can then be used in aggressor-victim-aggressor modelling in order to both predict circuit performance and to study transmitter and receiver equalisation schemes that may be required to open closed eyes.
The new models are rated to 30GHz end frequency, and can return S-parameter results out to 40GHz. This makes the devices suitable for crosstalk measurements on a wide variety of commonly deployed high-speed multi-lane serial data standards.
