BERTScope Digital Pre-emphasis
The DPP Digital Pre-emphasis Processor and LE Linear Equalizer are no longer available for purchase. The Tektronix BSX Series BERTScope® are recommended replacements. Information on these products is located at www.tek.com/bit-error-rate-tester/bsx-series-bertscope®-bit-error-rate-tester. Refurbished Digital Pre-emphasis Processor may be available from Tektronix Encore, www.tek.com/encore.
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.
Features |
Benefits |
| 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. |
