Operating Basics
DIAGNOSTICS Submenu
Use this menu to execute the diagnostic routines for the mainframe and installed
modules. The following
fi
gure shows the DIAGNOSTICS submenu.
Figure 2-24: DIAGNOSTICS submenu
CAUTION.
When you execute the diagnostic routines, be sure to save the current
instrument settings to a preset. After the diagnostics is completed, reboot the
instrument and then recall the saved settings.
Press the
ENTER
button to execute the diagnostic routines (note that the
GPS7 module has its own diagnostics submenu; running the diagnostics here does
not run the GPS7 diagnostics). If all of the diagnostic routines are completed
without any errors, the instrument will display "Pass".
If a diagnostic error is displayed, contact your local Tektronix Field Of
fi
ce or
representative.
NOTE.
The front-panel buttons are disabled until the diagnostic routines are
completed.
CAL OVEN Submenu
This menu can be accessed in regular or factory mode. When the instrument is
in regular mode, you can access the internal frequency calibration, which can be
performed while the instrument is in service. When the instrument is in factory
mode, you can access the internal frequency calibration and you can characterize
the oscillator frequency as a function of voltage. The latter characterization
is only available on the GPS7 module and should only be performed when the
instrument is out of service.
Internal frequency calibration.
Use this menu to set the internal frequency of the
mainframe internal oscillator. This may be done without removing the instrument
from service, allowing you to compensate for oven drift while the instrument
is in its operating environment. This menu only appears when the mainframe
has software version 5.1 or greater installed and when there is a GPS7 module
installed.
