Audio analyzers are compact Product News 12/21/2005 Post a comment Rohde & Schwarz is adding two compact audio analyzers to its Smart Instruments family. Models generate single-channel and dual-channel sinewave, two-tone, and noise signals.
50-MHz waveform generators include PLL capabilities Product News 12/19/2005 Post a comment Although technologies such as microwave RF, RapidIO, and PCI Express occupy the leading-edge limelight these days, not everyone needs GHz-domain test gear. There are still many applications for lower-frequency equipment. Fluke Corp., for example, has some function generators for 50-MHz or lower applications.
Battery powered vector network analyzers go afield Product News 12/14/2005 Post a comment Anritsu's got two portable handheld vector network analyzers that can make vector-corrected 1-port and 1-path 2-port measurements from 2-MHz all the way out to 6-GHz. Weighing just 6-lbs, these VNAs can replace racks of benchtop gear, and their USB and Ethernet hooks give you the connectivity needed to transfer data to other lab equipment. eeProductCenter Tech Editor Alex Mendelsohn reports.
OTN core switching tester gets OTU1 capabilities Product News 12/14/2005 Post a comment Broadband communications test-and-measurement house Innocor adds OTU1 test capabilities to an existing next-generation test equipment line for OTN. The adjunct addresses the needs of transport applications that require FEC and OTN Digital Wrapper testing at 2.666-Gbit/s line rates.
Low-power IC test can be trying Design How-To 12/5/2005 Post a comment Power is at a premium across mainstream applications ranging from battery-powered personal appliances to multiprocessor server farms. For designers, power management means controlling leakage power lost during standby mode as well as dynamic power consumption when multiple transistors switch in unison to perform desired functions. Designers address increased leakage current at more-advanced nanometer technologies through techniques such as multivoltage-supply design, using lower-supply-voltage d
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.
