Functionality Check
This procedure verifies that the signal generator powers up and that the internal instrument check
identifies no errors. The internal check evaluates the correctness of operation and returns an error
message if a problem is detected.
1. Turn power on to the signal generator by pressing the power switch. The green LED will light. Let
the instrument warm up for one hour.
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 turned on.
4. If the ERR annunciator is turned on, review the error messages in the queue by pressing Utility,
Error Info, View Next Error Message. The first error message in the queue will be shown in the text
area of the display. Refer to the error messages 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. Then 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 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.
