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.
