Tektronix Enhances Optical Modulation Analysis

April 30, 2012. Tektronix Inc. has announced that its OM4000 Series Optical Modulation Analyzer can now drive the DSA8300 Digital Sampling Oscilloscope to perform analysis on PM-QPSK, QAM, and other complex-modulation signals with higher vertical resolution than real-time based systems at lower total system cost.

With this enhancement to the OM4000, Tektronix said it is giving optical networking designers and manufacturers the flexibility to choose between real-time and equivalent-time acquisition systems to suit their measurement needs.

The OM4000 paired with the DSA8300 targets network-equipment manufacturers and designers who require higher vertical resolution than what can be accomplished with real-time oscilloscopes, or who are looking to lower overall system costs.  Key capabilities provided by the DSA8300 in this application include 16-bit vertical resolution and 450 µV RMS noise floor at 60 GHz for added dynamic range and accuracy, up to 60-GHz bandwidth on four channels to help future-proof the system for next generation baud rates, and timing jitter as low as 450 fs RMS to enable visibility into real signal performance.

“As the worldwide demand for bandwidth continues to grow at a rapid pace, our customers are being asked to find ways to increase the efficiency, data rates, and reliability of optical network equipment while at the same time reducing cost,” said Brian Reich, general manager, performance oscilloscopes, Tektronix. “With this enhancement to the OM4000 Series, we are meeting these needs with cost-saving flexibility, higher vertical resolution and future-proof levels of measurement bandwidth.”
