Performance Tests: Resident Self Tests
Resident Self Tests The M2540A Resident Self Tests (RST) are a suite of tests that verify system hardware, using no
external instrumentation.
The RST suite consists of tests for custom M2540A hardware and software. The Resident Self
Tests also exercise individual subsystems such as the acoustic processor and the beam former
processor.
The stand-alone RST application provides access to all the tests. RST also provides information
on hardware and software, and service information on the ultrasound system. System
information, test pass and fail results, and errors can be viewed, saved, and printed by the RST
application.
Availability
The RST application is available whenever the ultrasound application is running. You can also
launch RST as the system powers up. When it starts, the RST application stops the main
ultrasound application.
Logging On
To launch the RST application, see “Launching the RST Application” on page113. The RST
application opens with a logon window, which asks you to enter a user name and a password.
The logon window also includes a check box that skips the logon dialog the next time the RST
application is launched. Only service personnel can enable that option, and it only applies for
24 hours. After 24 hours, the logon dialog shows at launch, even if the option is selected.
Customers or service personnel who log on with a valid user name and password can create and
modify service log entries. See “Using the Service Log” on page 125.
If RST is installed on the system, logging on is not required.
