Deep memory logic analyzers kick it up a notch
Product News  
11/1/2006   Post a comment
Agilent Technologies expands its logic analyzer line-up with a modular mainframe, two logic analyzer modules offering up to 4X the available memory in the industry, and applications for developers of PCI Express and Altera FPGAs.

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.
