Service and Diagnostics Menus

Overview

Overview
The Service capabilities described below are accessed via the Service and
Diagnostic menus in the System menu. The Service capabilities are intended for
field service technicians. These technicians may be at an Agilent Service Center or
at a self-maintaining customer site.
There are two types of Service capabilities:
1. Diagnostics - These are available to any user and will assist in initial
troubleshooting of instrument malfunctions. Examples are the ability to read
the mechanical relay cycles.
2. Service Functions - These are for use by the factory or field repair technicians,
access is controlled. Examples are the ability to band lock the analyzer and
control the DAC which sets the 10 MHz Reference frequency.

Controlling Access

There are two levels of service and diagnostics capabilities:
1. "Regular access" to diagnostic capabilities that everyone is allowed access.
Care may be required to use a feature appropriately. This is the "Diagnostic"
type of Service capability defined above.
2. "Secure service access" to the Service menu. This prevents the casual user from
accessing and using these features. It is intended to provide this access to
Agilent Service Centers or any customer who purchases the Service Guide. The
"Service Functions" type of Service capability is defined above.
Access to secured service capabilities is gained through the Windows
Authentication (login). In addition, the technician is required to enter a specific
numeric Service Code that is controlled by the instrument software. The Service
Code is defined to be easily entered via the front panel; an external keyboard or
mouse will not be required. Once access has been gained, it persists within the
execution of the instrument application. If the user exits the instrument application,
they must re-enter the Service Code to gain access.

Secure service access

Secure service access is the Windows
"advanceduser" must be a member of the Power Users group. This account has not
been pre-configured on the instrument. The administrator must create the login and
make "advanceduser" a member of the Power Users group (refer to Windows XP
Help and Support Center). Agilent recommends using the password "service 4u"
to ensure the analyzer can be supported by multiple people. The Service Code is
"−2061".
