SML

Service Program

1 Service program

1.1 Overview

The SML Service Program is used to support troubleshooting and module testing. It enables operation

of the internal control bits and reading out of the available diagnostic points. In addition, the program can

be used to transfer basic remote-control commands. The program runs under Windows (95, 98, NT and

2000). The instrument can be remote-controlled via IEC bus or RS232 interface. External level calibra-

tion is possible in conjunction with a power meter of the type Rohde & Schwarz NRVD that is connected

to the IEC bus.

1.2 Installation

To install the program under Windows (95, 98, NT or 2000) insert the installation disk 1 into your drive

and call up the "setup.exe" file. Follow the instructions of the installation program. The service program

requires the CVI runtime engine, which will be installed if it is not yet available.

Program Description

To start the program click on "SML_SERV" in the start menu using the left mouse key (The path within

the start menu depends on the entries made during the installation). You may as well call up the

"smlserv.exe" file in the program directory.

1.3.1

Selection of the Interface

When the program is started, the user is prompted t to enter the desired type of connection to the SML.

It is possible to select between IEC bus (GPIB) and RS232 interface.

For configuration of the IEC-bus interface, all that is needed is to enter the IEC-bus address set on the

instrument. Before confirming using "OK" make sure that the connection cable is connected between

PC and SML.

Port COM1 is used for communication via the RS232 interface. The SML is connected to the PC via a

null modem cable. The configuration values set on the instrument are queried by the program.

1.3.2

Main View

The main view of the service program contains general information on the SML, the firmware, the mod-

ules and the options fitted. In addition, the current module temperatures and the error messages of the

instrument are displayed.

1.3.3

Module Test

Tests for the individual function modules of the SML are started by selecting the module in question in

the "Check" menu. The menu item "Check All" performs all module tests one after the other. During the

tests, internal diagnostic points are checked. The upper area of the module check window shows the

signal path of the module. During the test, the diagnostic points entered there are colored. Green points

represent circuit components that seemed to be okay to the program. Diagnostic points that are out of

the test tolerances are colored in red. In the lower part of the window, the tested points are listed in a

report. After completion of the test, the report can be opened in an extra window using the "Report" but-

ton. The report can then be stored, printed out or copied to the buffer.

1.3.4

Calibration

The menu item "Calibrate" permits to call up the calibration routines of the SML. A distinction is made

between internal and external calibrations. No additional measuring instruments are required for the

internal calibrations.
