Functional Check

In addition to the self tests, you can also perform an operational check of the

VX4380.

The VX4380 256-Crosspoint Relay Matrix Module executes a self test at

power-on, on direction of a VXIbus hard or soft reset condition, or on command.

The power-on self test consists of an interface self test and an instrument self

test. The self test requested by command performs only the instrument self test.

A VXIbus hard reset occurs when another device, such as the VXIbus Resource

Manager, asserts the backplane line SYSRESET*. A VXIbus soft reset occurs

when another device, such as the VX4380 commander, sets the Reset bit in the

VX4380 Control register.

During power-on, or a hard or soft reset, the following actions take place:

1. The SYSFAIL* (VME system-failure) line is set active, indicating that the

module is executing a self test, and the Failed LED is lighted. For a soft

reset, SYSFAIL* is set. All Tektronix commanders will simultaneously set

SYSFAIL INHIBIT to prevent the resource manager from prematurely

reporting the failure of a card.

2. On completion of the interface self test, SYSFAIL* is de-asserted. If the test

fails, the SYSFAIL* line remains active. If the interface self test passed, the

SYSFAIL* line is released, and the module enters the VXIbus PASSED state

(ready for normal operation). If it failed, the module enters the VXIbus

FAILED state.

3. The instrument self test, as described in the *TST? command description, is

then executed. This tests the Option 01 VXI Interface daughter board and

any relay modules under its control. If the self test fails, the module makes

an internal record of the failure(s) that occur.

The default condition of the Option 01 Module after the completion of power-on

self test is as follows:

All relays on modules controlled by the Option 01 (except VX4320

Modules) are set to the open position.

You can run the self test at any time during normal operation by using the *TST?

command. At the end of a self test initiated by this command, the module is

restored to its pre-test state.
