Engineers designing and validating backplane Ethernet need to monitor and debug multi-gigabit KR/KX protocol interface to ensure reliable operation of the system. In an emerging technology, engineers can test and debug designs with easy-to-use instruments such as oscilloscopes. Oscilloscopes normally provide extensive details about electrical characteristics of the signal. But engineers need more information such as protocol content at various protocol layers. In a versatile 1000Base KX/KR protocol standard, manually interpreting the protocol layer information using oscilloscope data is time consuming and prone to human error.

PGY-NEGO KX/KR Software runs on Tektronix DPO/DSA/MSO70000 oscilloscope series. PGY-NEGO Software KX/KR utilizes the hardware based real-time serial pattern trigger and long acquisition record length up to 200MB to provide superior DME and Line Training KX/KR Protocol Analysis Solution.

The industry’s first oscilloscope-based PGY-NEGO KX/KR Protocol Analysis software lets you see every event in the KR/KX stream.

PGY-NEGO KR/KX Protocol Analyzer software performs the KR/KX DME and Line Training compliance tests as per IEEE 802.3ap Standard. It provides unmatched flexibility in analyzing, debugging, and correlating the test results from KR/KX Frame to physical layer analog waveforms to address the multi-gigabit KR/KX design challenges.

For efficient debugging, PGY-NEGO KX/KR software provides unique viewers, which comprises of Analyze view, DME Detail view, DME field view and Detail view. Automatic cross-linking between all these viewers enables you to see and correlate the data in different parts of the Gigabit KR/KX protocol stack.

PGY-NEGO KR/KX Test Setup:
Clicking on PGY-NEGO KX/KR icon in oscilloscope desktop folder launches PGY-NEGO KX/KR Software installed in Tektronix oscilloscopes. Simultaneous view and control of oscilloscope waveform display as well as PGY-NEGO KX/KR Software. You can analyze KX/KR DME and Line training in single acquisition mode, in Repetitive mode and in No Acq mode. In No Acq Mode, KX/KR software analyses an already captured signal that is present in the acquisition memory of the oscilloscope.

PGY-NEGO KX/KR Software provides powerful protocol-aware trigger based on DME page content. Manchester violation timing can be set to capture the DME signals. Similarly protocol content of DME page content can be set to capture DME signals.

Comprehensive PGY-NEGO KR/KX Protocol Analysis
For efficient debugging and troubleshooting the Gigabit KR/KX protocol, PGY-NEGO KX/KR Protocol analysis software offers Analyze view, DME detail view, DME field view and Waveform view.

Analyze View:
Provides complete timing details (T1, T2, T3, T4, T5 and T6) for all the DME pages used in the Auto-negotiation Phase with summary of pass/fail test results of the corresponding timing window. Analyze summary view enables to quickly navigate to the failure frames for detailed analysis.

Detail view:
This feature helps the you to navigate from each DME page with flexibility of viewing the waveform, timing detail and 48bit field information for each DME page used in auto negotiation phase. This view correlates the waveform with annotated timing measurements, protocol packets of DME and Line training events.

Auto negotiation (DME) and Line Training Timing Measurements:

Timing Parameter Description
T1 Transition position spacing (period)
T2 Clock Transition to Clock Transition
T3 Clock Transition to Data Transition (data =1)
T4 Transition in a DME page
T5 DME page width
T6 DME Manchester delimiter width
Quiet Time Time between end of Auto negotiation and start of Line Training is indicated by the “Quite time”
Frame Marker Frames are delimited by the 32-bit pattern, hexadecimal FFFF0000
Coefficient Update Frame Marker have been identified and transferred , then it is followed by 16 Octets (128 bits ) for the coefficient update field
Status Report 128 bits of Status Report Field data is followed after the Coefficient update field data
Training Pattern The training pattern is a 512 octet pattern consisting of 4094 bits from the output of a pseudo-random bit sequence of order 11 (PRBS11) generator followed by two zeros

Documentation of DME and Line Training Analysis
PGY-NEGO KX/KR DME and Line Training Analysis software provides the flexibility of exporting the decode data in txt and csv file format. Report Generation allows you to have different waveforms images including the oscilloscope screenshot in the report. Report header, comments and Test attributes can be added.
