Overview; Controlling Access - Agilent Technologies N9039A Service Manual

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 select a specific RF Filter Path.

Controlling Access

There are two levels of service and diagnostics capabilities:
"Unrestricted access" - Access to the Diagnostics menu is allowed for
everyone. Care may be required to use a feature appropriately. This is the
"Diagnostic" type of Service capability defined above.
"Secure Service Access" - Access to the Service menu is restricted to the
service technician. This prevents the casual user from accessing and using these
features. The intention is to provide this access to Agilent Service Centers as
well as any self-maintaining customer who purchases the Service Guide. This
is the "Service Functions" type of Service capability defined above.
Access to secured service capabilities is gained via a specific user name through
®
the Window Authentication (login). In addition, the service technician is also
required to enter a specific numeric Service Code. The Service Code is designed to
be easily entered via the front panel; an external keyboard or mouse is not
required.
Once access has been gained, it will persist within the current instance of the
instrument application. If the user exits the instrument application, the Service
Code will need to be entered again in order to gain access to the Service Menu.
