Introduction

TLA5000 Series Logic Analyzers

The TLA5000 series logic analyzers consist of four portable logic analyzer mainframes, which differ by channel width, and all of the accessories and supports that are used with them. The logic analyzers are built upon the Microsoft Windows operating system, which allows you to install any PC-compatible, third-party hardware and software on the instrument.

A TLA5000 logic analyzer is illustrated in Figure i.

Operating Information

This chapter covers basic installation information and some high-level operating instructions. For detailed installation information, refer to the TLA5000 Series Installation Manual; for detailed operating information, refer to the online help.

Installation

The basic operating software is already installed on the hard disk. Use the information in this section to set up the instrument for service or to verify proper operation.

Before You Start

Environmental

Considerations

Chassis Ground

Connections

Verify that all parts and accessories for the logic analyzer are available.

The logic analyzer is designed to operate on a bench or a cart in the normal position (on the bottom feet).

CAUTION. Allow a 5.1 cm (2 in) clearance at the bottom and sides of the instrument to ensure proper cooling. Inadequate clearances can cause the instrument to overheat and shut down.

Use the chassis ground connections to connect the grounds of the target system (system-under-test) to the logic analyzer to ensure a common ground connection between instruments.

Figure 2--1 shows the chassis ground connection on the logic analyzer.

Connecting Probes

After you connect all the accessories, you can connect the probes to the instrument.

CAUTION. When attaching the probe to the logic analyzer, you must use care to evenly tighten probe screws until they are snug. First slightly tighten screws, then snug each screw to 4 in-lbs (max). Undertightening the probe screws can result in intermittent performance.

Connect the logic analyzer probes and the optional retaining brackets as shown in Figure 2--3. Not all probes use the screws to connect the retaining bracket to the probe; currently the P6418 and P6419 probes use the screws, while the P6417 and P6434 probes do not need the screws to hold the retaining bracket in place.
