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.

Performing the Incoming

Inspection

Checking the P64xx Logic

Analyzer Probes

(Optional)

After the power-on diagnostic finishes checking the basic functionality of the logic analyzer, you need to perform an incoming inspection. The incoming inspection consists of verifying the basic operation of the logic analyzer.

For a more detailed functionality check, run the following self-calibration and extended diagnostics procedures.

NOTE. Allow the mainframe to warm up for 30 minutes before running the self-calibration.

To run self-calibration and diagnostics, perform the following:

1. Disconnect any probes that are attached to the input connectors.

2. Select the System menu and click Calibration and Diagnostics.

3. Run the self-calibration and then the extended diagnostics by selecting the

proper tab. Results of the tests display on the individual property page.

Connect the P64xx logic analyzer probes to a signal source, start an acquisition, and verify that the acquired data is displayed in either the listing or waveform windows. You can also use the Activity Indicators in the logic analyzer Setup window to view signal activity at the probe tips.

Software Installation

NOTE. If you connect probes to any channels other than the A2 and A3 groups, you must define the groups and channels in the Setup window and set the threshold voltages before acquiring data on other probe channels.

The logic analyzer ships with the product software installed, so only perform these procedures if reinstallation becomes necessary.

The Windows operating system and drivers are factory installed on the logic analyzer hard disk. The hard disk Image CDs serve as a backup in the event that you have to restore the hard disk drive.

Adjustment Procedures

With the exception of the self calibration procedures, all other procedures must be completed using the performance verification software and the test fixture.

Figure 5--1 on page 5--4 shows the locations of connectors and test points on the test fixture. You may need to refer to this illustration when connecting probes and cables to the fixture.

Self Calibration

Self calibration is an internal routine that optimizes performance at the current ambient temperature to maximize measurement accuracy. No external equipment or user actions are needed to complete the procedure. The logic analyzer saves data generated by the self calibration in nonvolatile memory. Passing self cal provides a higher level of confidence of functionality.

NOTE. Performing the self calibration does not guarantee that all parameters operate within limits. Operation within limits is achieved by performing the adjustment procedures. Verification of operation within limits is accomplished by performing the performance verification procedures.

You can run the self calibration at any time during normal operation. To maintain measurement accuracy, perform the self calibration if the following conditions occur:

H After repair and replacement of any circuit board.

H It has been a year since the last self calibration was run.

1. Ensure that the instrument has had a 30-minute warm up before attempting the self calibration, and that the logic analyzer application is running.

2. Disconnect any probes connected to the logic analyzer.

TLA5000 Series Service Manual

3. Select Calibration and Diagnostics from the System menu.

4. Select the Self Calibration tab page.

5. Click the Run button to start the self calibration.

The self calibration takes several minutes to complete, depending on the number of channels. Upon successfully completing the self calibration, the status changes from Running to Calibrated, and the Date and Time field is set to the present.
