4 Installation Note E4400-90392
Checking Signal Generator Functionality
Use the following procedure to confirm that the signal generator powers up and that the
internal check identifies no errors. The internal check evaluates the operation of the signal
generator and returns an error message if it detects a problem.
NOTE
The signal generator must warm up for at least five minutes and all errors
must be cleared from the error queue before a firmware upgrade can be
successfully completed.
If errors exist in the error queue and a firmware upgrade is attempted, the
firmware upgrade will be unsuccessful; new DSP code cannot be upgraded
until the error queue has been cleared.
When signal generators with Option 1E5 are first connected to ac line
power, the error message
ERROR 514, Reference Oven Cold
occurs
which causes both the
OVEN COLD
annunciator and the
ERR
annunciator to
turn on.
After approximately five minutes, the
OVEN COLD
annunciator
automatically clears, but the ERR annunciator remains on until all errors
are cleared from the error queue.
To check signal generator functionality
1. Turn on power to the signal generator and let it warm up for at least five minutes.
2. Cycle power on the signal generator. The green LED should light and the signal generator
should perform a functionality check.
3. When the display lights, check to see if the
ERR
annunciator is on.
• If the
ERR
annunciator is on, review the error messages in the error queue by pressing
Utility
>
Error Info
>
View Next Error Message
. The first error message in the error queue
appears in the display text area. (Refer to the signal generator error messages
document for information about each error message.)
After resolving all problems causing errors, press
Clear Error Queue(s)
.
• If the
ERR
annunciator is off, the signal generator functionality check has passed.
