Real-time oscilloscopes achieve 70 GHz performance
The oscilloscope platform will deliver the performance and signal fidelity needed for applications such as 400 Gbps and 1 Tbps optical communications and fourth generation serial data communications. Tektronix also announced an investment program that will give customers a cost-effective migration path to the new platform.
The extraordinary gain in bandwidth performance, with improved signal fidelity, is due in part to the development by Tektronix engineers of a patent pending signal processing architecture called Asynchronous Time Interleaving. The real-time oscilloscope platform will also include a number of other enhancements and refinements to improve overall performance and measurement precision.
“With these latest innovations, Tektronix is continuing to push the envelope on what can be achieved in high-fidelity, high-speed data acquisition systems,” said Kevin Ilcisin, chief technology officer, Tektronix. “The development of the industry’s first production-ready Asynchronous Time Interleaving architecture is a significant breakthrough that will improve signal-to-noise ratio beyond the frequency interleaving approach used by competing oscilloscope vendors.”
The limitation of frequency interleaving approaches lies in how the various frequency ranges are added together to reconstruct the final waveform, a step which compromises noise performance. In traditional frequency interleaving, each analog-to-digital converter (ADC) in the signal acquisition system only sees part of the input spectrum. With Asynchronous Time Interleaving technology, all ADCs see the full spectrum with full signal path symmetry. This offers the performance gains available from interleaved architectures while preserving signal fidelity.
