Precision clock generator has 16-digit resolution Product News 1/12/2006 Post a comment Test equipment maker Stanford Research Systems has an extremely stable synthesized squarewave clock generator that can be driven across an RS-232 serial line from a PC, or used in an automated suite using GPIB. Otionally fitted with high-stability timebases, it provides 16-digit resolution and less than 30-ms settling time signals across a range extending from sub-audio 1-microHertz into the microwave regime at 2.05-GHz.
Unique form-factor Windows-based digital scopes debut Product News 1/11/2006 Post a comment Oscilloscope maker LeCroy has a line of digital oscilloscopes claimed to eliminate tradeoffs between performance, display size, and bench footprint. The WaveRunner Xi scopes fill the so-called “viewer” scope niche in the 400-MHz to 600-MHz domain.
Focus-On: Serious scopes help spot signals Product News 1/11/2006 Post a comment The engineer’s venerable friend—the oscilloscope—continues to evolve. Today’s scopes let you observe both analog and digital signals on wide buses, in fast serial I/O lanes, and at radio frequencies RF---in some case into the microwave regime.
LCR meter comes up to speed Product News 1/10/2006 Post a comment Test equipment vendor Agilent Technologies is dishing up a precision LCR meter that can be used on the bench or in fast automated test racks. It's also highly accurate and repeatable, with test frequencies from audio to 2-MHz. eeProductCenter Senior Tech Editor Alex Mendelsohn reports.
Mid-range realtime scopes capture multiple signals simultaneously Product News 1/4/2006 Post a comment Scope maker Tektronix is rolling out new-generation hardware that eliminates tradeoffs found in many digital storage oscilloscopes between sample rate, record length, and waveform capture rate. 500-MHz, 1-GHz, and 2.5-GHz models make use of IBM SiGe semiconductors to provide sample rates of 10-Gsamples/s on four channels and realtime over-sampling on four channels, with up to 16x oversampling on one channel and 4x on four channels---simultaneously.
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.
