Product Description

This section provides a brief description of the Tektronix P6800 Logic Analyzer Probes and adapters, information on attaching color-coded probe labels, and probe and adapter c

onnection instructions from the logic analyzer to the target system.

The P6800 L Logic Analyzer modules to a target system. The P6800 probes can be used with both TLA7Axx and TLA7Bxx modules. The P6810, P6860, and P6880 probes consist of 34 channels, while the P6864 probe consists of 17 channels.

NOTE. References to TLA7Axx Series Logic Analyzers also apply to TLA7Bxx

Series Logic Analyzers unless stated.

The P6880 probe is designed for connection only to the compression land pattern

gured for differential signals. The P6880 is not compatible with either the

You can compare P6434 Probe connection using the 34-Channel Compression-on-PCB to P6434 Mictor adapter. (See Figure 8 on page 11.) Note that the difference in clearance between the P6434 Probe connection and the P6434 Probe connection using the Compression-on-PCB to P6434 Mictor adapter is 3.68 mm (0.145 in).
