Boost Your Test Capabilities

The BERTScope DPP is the first 12.5 Gb/s instrument solution capable of programmable three-tap or four-tap
pre-emphasis for compliance testing to standards such as 802.3ap, Serial Attached SCSI, 10GBASE-KR backplanes,
DisplayPort, and USB 3.0 — and flexible enough for the next-generation 8 GT/s PCI Express® standard under development.

• 1 to 12.5 Gb/s range of operation
• 3- or 4-tap non-linear signal conditioner
• Pre-cursor or post-cursor adjustment
• Standards compliant
• Exceptionally easy setup
• Concurrent multiple domain views, including a frequency domain Bode plot
• Precise correction control for backplane ISI, optical effects, etc.
• Adjustable through tap weights or step response
• Differential output is amplitude and offset adjustable
• Integrated operation with a BERTScope or in a standalone fashion controlled by a user-supplied PC

Boosting the amplitude of the transition bits in a digital signal, or pre-emphasis, is an increasingly common method employed in systems to over­come the frequency dependent loss of low cost circuit boards to allow the passage of Gb/s data. The BERTScope DPP covers the requirements for high data rate test, allowing the flexibility to evaluate compliance to multiple standards and to explore the limits of device performance.

A key benefit of the DPP is the ease with which an engineer can adjust the precise characteristics of the pre-emphasis signal being applied to the test device. This is achieved through a highly intuitive control interface that simultaneously shows the step response, tap weightings, and frequency response of the signal, in keeping with the BERTScope philosophy of multi-domain insight.
