Adjustment Procedures
TDS7104 & TDS7054 Service Manual
5-3
Overview of the Procedure
To perform this procedure you must have the specific equipment listed in
Table 5--2. You can use a separate computer as the instrument controller, or you
can install a GPIB controller card into the oscilloscope and use the PC that is
built into the oscilloscope as the controller. If you use the oscilloscope as the
controller, you must also have a keyboard and mouse attached to the oscilloscope
to operate the test program.
After the controller is set up, you need to install the performance verification test
program from a C D-ROM that was shipped with the oscilloscope. An installa-
tion wizard will assist you with the installation of the test program.
After the performance verification test program is installed, you need to install
the adjustment program contained on the CD that is included with this manual.
The adjustment program adds the adjustment procedure to the performance
verification test program. Once the adjustment program is installed, you can run
either the performance verification or adjustment procedures.
When you start the test program a screen of introductory information is
displayed that contains instructions, a text entry line, and function buttons. You
use these controls to navigate through the steps of the test program. You can
either click (or touch) the function buttons in the screen or use the function keys
on the keyboard. The keyboard is required for text entry. One of the initial
screens asks you to choose whether you want to execute the performance
verification or the adjustment procedure.
The adjustment procedure is fully automated. Once the program is started, all of
steps will run without manual intervention (CHAN_DELAY_C AL may require
manual intervention). The overall time to complete the adjustment is about 30
minutes. Every 30 days or when a head on the base unit is changed, a head skew
table is generated and will require moving the heads between channels.
When the adjustment is complete, you can save or print a report that lists the test
names and their exit status. The test report is an ACS II text file written to the
directory C:\tekcats\rpt\. The filename of the report is <oscilloscope
model>.<serial number>. If you have previously run the performance
verification procedure, the adjustment results are appended to the end of the
existing report file.
