Probe Design Information for P6810/6860/6880

Radically speed the discovery of digital signal integrity issues

The P6810/6860/6880 Logic Analyzer probes are used with TLA7Axx Logic Analyzer Modules to provide simultaneous analog and digital measurements through a single probe.

• Simultaneous analog and digital through the same logic analyzer probe
• Connectorless, high-density probing (P6860/80)
• Z-axis compression elastomer contact (P6860/80)
• 0.7 pF total capacitive loading
• Single-ended and full differential probing
• 300mV minimum signal swing single-ended
• 150mV minimum signal swing both sides differential
• Adapters for forward and backward compatibility

P6810 (TLA7Axx Option 2P) - The P6810 is a 34 channel general-purpose probe with differential clock, differential data for use when 1) probing individual test points within your target system, either directly or with a test clip, or 2) direct connection to legacy TLA family processor/bus support probe adapters with 8 channel probe connectors. The P6810 works with a wide-range of industry-standard probing accessories for flexible attachment to your target system.

P6860 (TLA7Axx Option 3P) - The P6860 is a 34 channel high-density compression probe, with differential clock and single-ended data. This probe utilizes a connector-less probe attach mechanism for quick and reliable connections to your system under test. This probe is recommended for those applications that require higher signal density or a connector-less probe attach.

P6880 (TLA7Axx Option 4P) - The P6880 is a 34-channel high-density compression probe with differential clock and differential data. This probe utilizes a connector-less probe attach mechanism for quick and reliable connection to your system under test. This probe is recommended for high-density applications that require a full differential probe.

Technology

The P6810/6860/6880 logic analyzer probes are the world's first logic analyzer probes to make use of Silicon Germanium (SiGe) technology. These new logic analyzer probes capitalize on technology that is being utilized by Tektronix TDS oscilloscopes today.

SiGe technology provides break-through probing performance by utilizing a time-proven, reliable elastomeric interface and providing a very short probe stub length.
