The BERTScope product family offers several Digital Signal Processing accessories to serve high speed serial designer needs in areas of Pre-Emphasis or Equalization.
The Digital Pre-emphasis Processor DPP Series takes in single-ended inputs of data and clock and conditions the signal by adding precision amounts of pre-emphasis for use with Bit Error Rate Testers. Nine Tap Linear Equalization supporting speeds up to 32Gb/s is supported with the LE320 Series remote head, offering compact two channel precision equalization.
|Range of operation 8Gb/s to 32Gb/s||Supports emerging 100G, COMM standards and similar technologies operating with physical line rates up to 32Gb/s.|
|Standard 4 tap (optional 9 Tap) equalization||+-20dB dynamic range on 4 standard taps and optional 9 taps filter designs supports a wide range design functions.|
|High Pass Filter designs||Required to model signal Pre-Emphasis or Continuous Time Linear Equalization operations.|
|Low Pass Filter designs||Support channel or backplane emulation.|
|General purpose signal amplification||Apply 20dB low noise gain to any differential signal.|
|Channel or Backplane De-Embed operations||Open eye and compensate for loss effects of long cables or interconnects.|
|0V-2.7V variable gain with return to zero||Precision output level controls permit signaling from “0” (Return to Zero) to 2.7 V differentially.|
|Standalone operation||Operated on a BERTScope or a user’s standalone PC supporting a wide set of operational models.|
|Fixed tap delay design||Eliminates external reference clock requirements.|
|Jitter pass through||Allows generator base sinusoidal, random jitter and bounded uncorrelated jitter components to pass from input to output un-impeded.|
|User configurable DDJ||Through precision channel loss modeling, fine grain DDJ synthesis is offered to designers.|
|S-Parameter Importer||Allows users to define the LE320 channel response as an approximation of a user loaded touchstone file of a physical system.|
