Rambus to detail ultra low power I/O technology News & Analysis 1/29/2007 Post a comment Rambus Inc. is expected to plow new ground in high speed, but low power interconnects with a paper at the International Solid State Circuits Conference in February detailing a technique to deliver I/O at power rates as little as 2miiliWatts per Gbit per second.
Networked IEEE-1588 clocking ensures timing, frequency measurement Product News 1/25/2007 Post a comment In some test-and-measurement applications, ensuring high accuracy time transfer over probabilistic networks is desirable. Symmetricom's XLi IEEE 1588 Grandmaster Clock, with its GPS reference, implements the IEEE-1588 Precision Time Protocol protocol to ensure accurate synchronization over Ethernet LANs.
Scope/analyzer gets phase-noise, spectral jitter analysis Product News 1/22/2007 Post a comment With modules and software for high-speed serial device characterization and signal integrity measurement, Agilent Technologies rolls out phase-noise application software and options for the company's popular DCA-J digital communications analyzer/scope. Both hardware and software enhancements are billed by Agilent as industry-firsts.
Gbit/s pattern generators get options Product News 1/18/2007 Post a comment Providing options to hasten characterization of high-speed interfaces, Agilent Technologies introduces pattern generators with jitter injection capabilities. Useful to 7-Gbit/s and 12.5-Gbit/s, these pattern generators now let you accurately stimulate serial high-speed ports with all types of jitter.
Ultra Mobile PC hosts RF spectrum analyzer Product News 1/16/2007 Post a comment Check out this handheld wireless spectrum analyzer running on a Pentium-based Windows XP tablet PC. Its calibrated receiver can measure popular wireless bands, including those for Wi-Fi, Wi-MAX, ISM, and Bluetooth.
Spectrum analyzer zeros in on cellular technologies Product News 1/9/2007 Post a comment Slated for low-frequency applications, a baseband analyzer from Rohde & Schwarz is tailored to the requirements of chipset development for cellphones and cellular base stations. With a frequency range up to 36 MHz, it can make measurements ahead of RF signals and measure I/Q signals at baseband.
Handheld analyzer displays eye patterns Product News 1/8/2007 Post a comment Working with high-speed serial data? Then look at this battery-powered handheld that can make PHY layer eye pattern measurements. It can be used with interfaces at OC-192/STM-64, 10G Fibre Channel, and 10G Ethernet data rates. With two electrical inputs you can peruse eye patterns, pulse patterns, and make mask compliance measurements at speeds to 12.5-Gbits/s.
Vector signal generator attacks EVM price barrier Product News 1/3/2007 Post a comment Here's news of a moderately priced signal generator that develops digitally modulated as well as CW signals in the 800-MHz through 1-GHz band, and in the 1.7-2.2-GHz cellular band. The instrument's I/Q generator produces high-accuracy signals for any digital modulation scheme used in these bands.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
