Check Signal Generator Functionality

Check 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, causing 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 list on the documentation CD 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.
