WARNING Before you disassemble the instrument, turn the power switch off and
unplug the instrument. Failure to unplug the instrument can result in
personal injury.
CAUTION Electrostatic discharge (ESD) can damage or destroy electronic components. All

Functionality Check
This procedure verifies that the signal generator powers up and that the internal instrument check
does not identify any errors. The internal check returns an error message if a problem is detected. It is
recommended that this procedure is performed prior to installing the upgrade kit.
1. Switch on the instrument line power. The green LED will light. Let the instrument warm up for
at least 5 minutes.
2. Cycle the power to the signal generator. The green LED should again be lit and the instrument will
perform a check.
3. When the display is lit, check to see if the ERR annunciator is displayed.
4. If the ERR annunciator is displayed, review the error messages in the queue by pressing Utility,
Error Info. The first error message in the queue will be shown in the text area of the display. Refer to
the service guide for information about the error message.
If there is more than one error message (each message will be designated as 1 of n), continue
pressing the View Next Error Message softkey until you have seen all of the messages.
5. When you have resolved all of the error messages, press Clear Error Queue(s) to delete the messages.
Afterwards, restart this procedure at step two.
NOTE For instruments with Option 1E5, ERROR 514, Reference Oven Cold will
occur whenever the signal generator is first connected to the AC line power. This
error cannot be cleared from the error queue until the internal reference has
warmed up (up to approximately 5 minutes).
