Interpreting Analyzer Messages

Factory DLP, not adaptable (U)

Indicates that the downloadable program or variable that you have

selected is used by a “personality” and cannot be edited. A personality is

a program that is manufactured by Agilent Technologies and is

available for use with the 8590 Series analyzer. An example of a

personality is the 85716A CATV system monitor personality.

FAIL: XXXX XXXXXXXXXX (H)

A circuit-test failure was detected by the central processing unit (CPU)

during power-up or instrument preset. A failure code has two major

parts: a 4-digit code followed by a 10-digit code. The 10-digit code

contains three separate failure codes. Each failure code must be

converted from hexadecimal to binary before it can be interpreted,

using Table 14-3 through Table 14-6.

Component-level information is provided with this error message

description. Refer to the 8590 Series Analyzers Component-Level Repair

Service Guide binder for further information about the indicated

components.

The Four-Digit Failure Code

The four-digit failure code identiﬁes the circuit location of the failure on

the A16 processor/video assembly. Component-level failure information

is also provided. Each digit of the four-digit hexadecimal segment must

be translated to its binary equivalent before using Table 14-3 to locate

the probable failure.

The 16 LEDs along the right-hand side of the A16 assembly provide the

same error information that is contained in the 4-digit failure code. Use

Table 14-3 to interpret the illuminated LEDs for an instrument failure.

Here is an example of a failure code. It is unlikely that an analyzer

would have so severe a failure involving all the components indicated.

The example is for demonstration only.

FAIL: DF40 0625C1F72D

The four-digit failure code (DF40) is interpreted in Table 14-3. The three

fail codes within the 10-digit section (0625C1F72D) are interpreted in

the “The 10-Digit Failure Code” description.
