Speciﬁc Considerations for Testing Link Power Management States, Link Degradation, and Link Training

If you intend to observe the timing of link transitions (link width, power savings

st that must be noted.

Detector Channe ls and

istener Channels

The serial analyzer module can accurately detect when a link transitions to and

rom a link state where no data is transmitted on the link. The module recognizes

f these link transitions by detecting the presence or absence of electrical signals only on lanes connected to the top and bottom channel on each connector (two of the four channels on each connector). All other channels infer the presence or absence of electrical signals by "listening to" these channels. By default, each of the two listener c hannels on each connector are set to listen to one of the two detector channels on that connector.

Any listener channel on connector A or B can be assigned to listen to any detector channel on connector A or B. Any listener channel on connector C or D can

On each probe connector the top and bottom channel are deﬁned as detector channels. The center two channels of each connector are deﬁned as listener channels.

To temporarily bypass the detectors to observedataonalllanesataslower transition detection rate, turn off the L0s detection. (See Bypassing the Detectors.)

When the serial analyzer module Transfer Rate is set to Track Training and an electrical idle occurs longer than the speciﬁed timeout, the module switches the acquistion rate from 5 GT/s to 2.5 G T/s. An electrical idle can happen when the system under test has shut down and starts up again in 2.5 GT/s mode.

Here is an example of a situation when you should use this setting:

A x4 link on a mid-bus footprint has been mistakenly wired in a non-standard format, so that Lane 0 is connected to Channel 1 instead of Channel 0 (connector A). It is not clear where Lane 0 is. Channel 1 listens to Channel 0 (default), but when the link trains down to a x1 (on Channel 1), Channel 1 is listening (and detecting) an electrical idle signal on Channel 0. It appears that the link is in an electrical idle state when it is not. When you turn the detection off, you can see that the footprint or the module-end probe connector must be rewired.

Diagnostics

This section contains the information needed for periodic and corrective maintenance of the serial analyzer modules.

Theserialanalyzermoduleperformspower-on diagnostics each time you power on the mainframe. The Calibration and Diagnostics property sheet appears at power-on if one or more of the diagnostics fail.

Power-On Diagnostics

Extended Diagnostics

Power-on diagnostics check basic functionality of the serial analyzer at every power on. If any failures occur at power on, the screen displays the calibration and diagnostics property sheet.

If there are no diagnostic failures when you power on the mainframe, display and run the calibration and diagnostics property sheet by selecting Calibration and Diagnostics from the System menu.

The extended diagnostics execute more thorough tests than the power-on diagnostics. Using the extended diagnostics, do the following tasks:

Run tests individually or a s a group

Run tests once or continuously

Run tests until failures occur

NOTE. For best results, only run the diagnostics with the probes disconnected

from the module.

To run the extended diagnostics, do the following steps:

1. Disconnect the probes from the serial analyzer module.

2. Start the TLA application if it is not already running.

3. From the System menu, select Calibration and Diagnostics.

4. Select the Extended Diagnostics property page.

5. Select the individual tests, group of tests, or all tests.

6. Click Run to start the extended diagnostics.

While the tests are executing, the word Running displays adjacent to the tests. When the tests are complete, either a Pass or Fail indication displays adjacent to each test.

Care and Maintenance

Exterior Inspection

1. Verify that the

probe is correctly connected to the module and to the SUT.

2. Move the suspected probe to another probe connection on the SUT and observe if the problem follows the probe. If the problem does not follow the probe, the module may be faulty.

3. Substitute the suspected probe with a known good probe and observe if the problem is still present. If the problem still occurs, the module may be faulty.

Inspection and cleaning are done as preventive maintenance. Preventive maintenance, when done regularly, may prevent malfunctions and enhance reliability.

Preventive maintenance consists of visually inspecting and cleaning the instrument, and using general care when operating it. How often to perform maintenance depends on the severity of the environment in which the instrument is used. A proper time to perform preventive maintenance is during an incoming inspection.

Inspect the outside of the instrument for damage, wear, and missing parts. (See Table 16.) Instruments that appear to have been dropped or otherwise abused should be checked thoroughly to verify correct operation and performance.

Cleaning Procedures

Contact your local Tektronix representative to repair any defects. In particular, immediately repair any defects that can cause personal injury or lead to further damage to the serial analyzer module or mainframe where it is used.

Inspect and clean the instrument as often as operating conditions require. Collection of dirt on internal components can cause them to overheat and breakdown. Dirt acts as an insulating blanket, preventing efﬁcient heat dissipation. Dirt also provides an electrical conduction path that can cause failures, especially under high-humidity conditions.
