Error Messages
Non-Recoverable Firmware Error
Non-Recoverable Firmware Error
This error occurs when the Test Set encounters a condition that the
firmware doesn’t understand - causing the Test Set to halt operation
until power is cycled. The message appears in the center of the Test
Set’s display and (except for the two lines in the second paragraph) has
the form:
Non-recoverable firmware error. Please record the 2 lines o
ftext below and contact Agilent Technologies through
your local service center or by calling 1-800-827-3848
(USA, toll-free)ask to speak to the 8935 Service Engineer.

Follow the instructions in the message.
Unfortunately, you cannot recover from this condition without turning
the Test Set off. The error may not reoccur when you turn the Test Set
back on and rerun the test where the error message first occurred. If
the failure reoccurs, you should record exactly what the configuration of
the instrument was when the error appeared, and contact Agilent. This
information will help us determine the proper course of action for your
repair.
If This Error Occurs at Power-Up
If the Test Set displays this error when first powered up, disabling Test
Set operation, it could be related to the
Autostart
field on the main
TESTS screen. This field causes the Test Set to automatically run the
last program loaded in memory when the Test Set is powered up. If the
program is corrupted, the Test Set will automatically “lock up.”
The only way to recover from this condition is to clear the Test Set’s
operating RAM. This will clear any IBASIC program, Save/Recall
registers, and RAM disks that have been saved, as well as three
calibration factors. The calibration factors are easily re-entered; the
IBASIC programs, Save/Recall registers, and RAM disks must be
re-loaded or re-initialized after clearing memory.
To clear the Test Set’s RAM:
1. Turn the Test Set off.
2. Hold the
Code Dom
and
HZ/
µ
V
keys down.
3. Turn the power on (with the buttons still held down) and wait until
the initial power-up screen is displayed.
