Service Guide
16 Service and Diagnostics Menus
Overview
The Service capabilities described below are accessed via the Service and
Diagnostic menus under the System menu. The Service capabilities are
intended for field service technicians. These technicians may be at an Keysight
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 and access to these functions is controlled. Examples are the
ability to select a specific RF Preselector Filter Path.
Controlling Access
There are two levels of service and diagnostics capabilities:
1. “Unrestricted Access” - Access to the Diagnostics menu is allowed for
everyone. Care may be required to use a feature appropriately. This is the
“Diagnostics” type of Service capability defined above.
2. “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 level of access to Keysight
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 numeric
Service Code. The Service Code is designed to be easily entered via the
front panel; an external keyboard or mouse is not required.
