Getting started
This chapter gives you an overview of the program, explains how to start
and stop it and provides some basic aspects that you need to know.
2.1 Beginning a session
The tuner program can be started in three ways:
• Selecting the
Tuner...
button in the
Tools
menu of the acquisition pro-
gram. Measurements using acquisition program should be stopped
before starting the tuner. See “Data acquisition User’s Manual” for
details of the acquisition program.
• Using the graphical user interface of the operating system by double
clicking the tuner icon in “Maintenance” toolbox under the “MEG
analysis” toolbox.
• Giving a suitable command in UNIX shell. For the proper command
and options, refer to Appendix A.
Only one tuning program should be running at any time. If the tuning pro-
gram is already running on the same system, the new starting program
shows an question dialog warning about the already running program. In
such a case you should answer
OK
to stop the new one and find out who is
running the program. It is possible that you get this message even if there
is no other instance of the program running, for example if the program
was killed or it died unexpectedly. If you are sure that there is no other
copy running you can go on using the program by responding with
Can-
cel
button.
After starting the program, a user interface similar to Figure 2.1 appears.
On the top of the window is a menu bar that allows access to several oper-
ations and parameter settings. Major part of the window area is taken by a
graphics area which is used to show the results of current operation. On
the left are controls to show and alter manually the SQUID working point
parameters and two large buttons that are used to initiate and stop opera-
tions. These buttons will be called “start button” and “stop button”
throughout the manual. The labels on these buttons change depending on
the situation. In the bottom of the window is a status display area and con-
trols to alter graphics display scales.
