Logic Analyzer Probes
The NEX-PRBx-xx Probe Family
- High Speed Passive Connection to Tektronix Logic Analyzers
- Low Cost Solutions for Embedded Designs
- Used with Nexus Technology Interposers/VDIMMs
- Up to 1,333MT/s Acquisition in DDR3 Applications

Overview
The NEX-PRBxxx probes are high speed, passive logic analyzer probes designed to fit in mechanically tight applications. Connection to the target are made at a right angle, greatly reducing the probe vertical keep-out relative to other logic analyzer probes. These probes require the placement of a probe input termination resistor on the target.
Typical Applications
These probes were designed for high speed parallel applications including:
- Up to 1,333MT/s Parallel Applications
- DDR3
- DDR2
Tektronix Logic Analyzer Modules Supported
The following Tektronix logic analyzer modules are supported.
| TLA Modules Supported |
|---|
| TLA7BBx |
| TLA7ACx |
| TLA7ABx |
HCD Passive Logic Analyzer Probes
The HCD passive logic analyzer probes (NEX-PRBx-XL) provides a connectorless, low profile, and passive interface to a target for parallel acquisition up to 1,333MT/s. The following probes are available:
| Nomenclature | Input Channels | TLA Channels Used | Notes |
|---|---|---|---|
| NEX-PRB1-XL | 34 | 34 | Direct Connect to TLA |
| NEX-PRB2-XL | 34 | 68 | 2x TLA Demux Support |
These probes come with all the hardware necessary to connect to the target footprint. For illustration, the following images show the application of the NEX-PRB1-XL probe for use with the logic analyzer component interposer.
