Verifying the Functionality of the Signal Generator
Power On the Signal Generator and Check for Error Messages
This procedure verifies that the signal generator powers up and that the internal instrument check
identifies no errors.
1. Turn power on to the signal generator by pressing the power switch. The green LED will light. Let the
signal generator warm up for one hour.
2. Cycle the power to the signal generator. The green LED should again be lit and the signal generator
performs a check.
3. When the display is lit, check to see if the
ERR
annunciator is turned on.
4. If the
ERR
annunciator is turned on, review the error messages in the queue by pressing
Utility
>
Error Info
. The first error message in the queue is 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), press 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.
Then restart this procedure at step two.
NOTE
For signal generators with Option 1E5,
ERROR 514, Reference Oven Cold
will occur
whenever the signal generator is first connected to AC line power. The
OVEN COLD
annunciator and the
ERR
annunciator will both turn on. The
OVEN COLD
annunciator will
automatically clear after approximately 5 minutes. The error queue cannot be cleared,
however, until the
OVEN COLD
annunciator has turned off.
