Tektronix offers several Digital Signal Processing accessories to serve high speed serial designer needs in areas of Pre-emphasis or Equalization when using the BSA Series Bit Error Rate Tester.
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.

Benefits |
Supports emerging 100G, COMM standards and similar technologies operating with physical line rates up to 32Gb/s. |
+-20dB dynamic range on 4 standard taps and optional 9 taps filter designs supports a wide range design functions. |
Required to model signal Pre-Emphasis or Continuous Time Linear Equalization operations. |
Support channel or backplane emulation. |
Apply 20dB low noise gain to any differential signal. |
Open eye and compensate for loss effects of long cables or interconnects. |
Precision output level controls permit signaling from “0” (Return to Zero) to 2.7 V differentially. |
Operated on a BERTScope or a user’s standalone PC supporting a wide set of operational models. |
Eliminates external reference clock requirements. |
Allows generator base sinusoidal, random jitter and bounded uncorrelated jitter components to pass from input to output un-impeded. |
Through precision channel loss modeling, fine grain DDJ synthesis is offered to designers. |
Allows users to define the LE320 channel response as an approximation of a user loaded touchstone file of a physical system. |
