Step 2: 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. The internal check evaluates the correctness of
operation and returns an error message if a problem is detected.
1. Switch on the signal generator. Let the signal generator warm up for at least five
minutes.
NOTE For ESG-AP, ESG-DP, and Option 1E5 signal generators, ERROR 514,
Reference Oven Cold will occur whenever the signal generator is powered
up within five minutes of being 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 five minutes. The
error queue cannot be cleared, however, until the
OVEN COLD annunciator has
turned off.
2. Cycle the power to the signal generator and verify that the green LED on both the front
and rear panels is lit. Refer to Figure 1-1.
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 descriptions
of error messages.
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 and recorded all
of the messages.
5. If you were able to resolve all of the error messages, press Utility > Error Info >
Clear Error Queue(s) to delete the list of error messages.
