PM50 Tool
Overview
The WAVECREST PM50 option enables the user to obtain compliant jitter measurements. By inputting
a data stream with a repeating pattern into a SIA-3000 channel card, the user can gather quantitative
information on DJ, RJ, PJ, DCD&ISI and their contribution to Total Jitter.
Functions of the PM50
• Generate a pattern marker based on pattern match at discrete data rates or in edge count for data
rates up to 5Gb/s.
• Generate a marker for many data standards such as Fibre Channel, InfiniBand, Gigabit Ethernet,
Serial ATA and XAUI to enable jitter compliance measurements.
• Record and display bit errors in pattern match mode.
Applications of the PM50 Option Using the Known Pattern with Marker Tool
• Analyze a data pattern and decompose or separate the various jitter components so the designer can
better understand and improve system performance.
• Measure the Deterministic Jitter (DJ) components: Duty-Cycle Distortion and Intersymbol
Interference (DCD+ISI), Periodic Jitter (PJ).
• Measure the Gaussian—or Random Jitter (RJ) component.
• View DCD+ISI relative to pattern transition density.
• Compliance testing Fibre Channel, Gigabit Ethernet, InfiniBand and XAUI devices.
• Advanced (not covered in this guide): View jitter data and model the signal as seen by the receiver,
filtering RJ and PJ or altering acquisition configuration.
