Verify Operation

To verify the operation of the MTM400 monitor, you will need to access the instrument RUI using a PC meeting the system requirements listed in Table 2. The MTM400 monitor and the PC need to be connected to the same Ethernet network.

Table 2: MTM400 monitor RUI platform requirements

Characteristic Description

Minimum Specification 1 GHz Intel Pentium Processor (Preferred: 2 GHz)

Operating System Microsoft Windows operating systems Windows 2000 or Windows XP

(Recommended: Windows XP Pro)

Disk space 2GBfreediskspace

Ethernet 10/100-base T

Installed software Microsoft Internet Explorer, Version 6.0 minimum;

Microsoft Java Virtual Machine installed, Version 5.0 minimum

RAM 1GB

CD-ROM Drive 8x

Display 1024 x 768 pixel video monitor with 16 available colors

Perform the following steps to verify that the MTM400 monitor and the 8VSB interface card you reinstalled are operating properly:

NOTE. This procedure assumes that the MTM400 monitor is operating with firmware version 2.6.1.

1. Connect the MTM400 monitor to an Ethernet network, power up the

instrument, and then wait for the instrument to initialize. When the initialization process is complete, the instrument beeps and the front-panel LEDs illuminate.

F-Connector Replacement for 8VSB Interface

Replacement Instructions -- MTM400 Monitor

2. Using a PC connected to the same Ethernet network as the MTM400

monitor, perform the following steps to open the MTM400 monitor RUI:

NOTE. The following procedure uses Microsoft Internet Explorer to open the MTM400 monitor RUI. You can also access the RUI using the Tektronix Web Monitoring Systems Manager (WebMSM). The instructions for using WebMSM are located in the WebMSM User Manual (Tektronix part number 071-1239-xx).

a. Launch Microsoft Internet Explorer.

b. In the address bar of the Web browser, enter the network identity or

IP address of the MTM400 monitor, for example: http://TSMonitor01 or http://111.222.333.444.

When you press the Enter key, a Java applet is downloaded from the MTM400 monitor and launched. The file size is approximately 1.5 MB; the download time will depend on the network speed and traffic.

CAUTION. The Java applet will not run unless a temp directory is properly configured on the PC. A temp directory is set up by default in the Windows XP operating system; previous operating systems may require operator action.

The Java applet will not run unless the Microsoft Java Virtual Machine is installed. Type jview at the command prompt to verify that it is installed and that the version is 5.00.3809 or greater. If it is not installed, obtain the installation file from the Tektronix Web site.

If the Sun Virtual Machine has also been installed, the Sun Virtual Machine must not be set as the default in the Java control panel or Internet Explorer options, advanced tab.

3. After the Java applet is downloaded, the MTM400 monitor splash screen

will appear, and then be quickly overlaid by the Login Details dialog box (see Figure 8).

4. In the Login Details dialog box, select Administrator from the User

drop-down list.

NOTE. Do not select User from the drop-down list. The User login type does not have sufficient permissions to perform software option upgrades.

5. Enter the appropriate password, and then click OK to accept the login

details. The default password for the Administrator login type is tek.

Replacement Procedure

Perform the following steps to replace the F-connector on the 8VSB interface module in your MTS400 Series system.

Preparation

Remove the Cabinet

If necessary, disconnect any signal and power cables from the instrument, and then place the instrument on a static-free workbench.

1. Install the protective cover on the front of the instrument and place the

instrument on the working surface with the rear panel facing up.

2. Remove the handle from the side of the instrument and remove the four feet

from the rear of the instrument (see Figure 12). Retain the screws for reinstallation.

Replacement Instructions -- MTS400 Series Systems

WARNING. To prevent damage to the EMI shielding and injury to yourself, use care when touching the EMI shielding strips around the front of the chassis. If you accidentally bend the “fingers” of the strip, it could create sharp protruding edges, which may cut you as you handle the chassis.

3. Position a flat blade screwdriver below the PEM nut on the rear panel as shown in Figure 13. Use the screwdriver as a lever to pry the cabinet loose from the chassis. Loosen each side alternately until the cabinet is released from the EMI gasket.

4. Slide the cabinet up and off the chassis.
