266 Keysight Technologies N9040B UXA Signal Analyzer Service Guide
Service and Diagnostics Menus
Overview
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 Keysight Service Centers or any customer who purchases the
Service Guide. The “Service Functions” type of Service capability is
defined above.
To access secured service capabilities 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
To access the secure service capabilities press System, Service with the
instrument application running. At this point you will see the window shown in
Figure 13-1. Enter the Service Code and press Login.
The Service Code is: -2061
Figure 13-1 Service Code Entry
The Service Diagnostic menus are split into two separate locations for the Multi-touch user
interface. They are available through the System -> Service menu and under the SA mode
Measure Setup menu. Both menus require that you first login via the System -> Service menu.
