Safety Considerations
WARNING Before you disassemble the instrument, turn the power switch off and unplug the signal
generator. Failure to unplug the signal generator can result in personal injury.
CAUTION Electrostatic discharge (ESD) can damage or destroy electronic components. All work on
electronic assemblies should be performed at a static-safe workstation.
Check Signal Generator Operation
Use the following procedure to confirm that the signal generator powers up and that the internal diagnostic check identifies
no errors. The internal check evaluates the operation of the signal generator and returns an error message if it detects a
problem.
1. Turn on the signal generator and let it warm up for at least five minutes.
NOTE When signal generators with Option 1E5 are first turned on, the reference oven will be cold and an error
message ERROR 514, Reference Oven Cold appears on the front-panel display. In addition, both the
OVEN COLD annunciator and the ERR annunciator appear on the front-panel display.
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.
2. Run the instrument self test. Press Utility > Instrument Info/Help Mode > Self Test > Run Complete Self Test. Upon
completion of the self test, a summary is displayed. Use the service guide to troubleshoot any failures detected by the
self test.
NOTE Some circuits may require up to 50 minutes to warm up before passing the self-test. If self-tests continue to
fail after 50 minutes of warm up, troubleshoot the instrument.
3. Check to see if the ERR annunciator is on.
•IftheERR 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 document for information about each error message.)
After resolving all problems causing errors, press Clear Error Queue(s).
•IftheERR annunciator is off, the signal generator operation check passed.

Make a backup copy of the Internal Waveform(s) from non-volatile memory
Perform the following steps to make a backup copy of the waveform(s) stored in the internal non-volatile memory
prior to installing the hard drive.
CAUTION Without performing this step, once the hard drive is installed, the waveform(s) will no longer be
accessible and removal of the hard drive by unplugging the W26 ribbon cable would have to be done
to re-access the waveform(s).
Using the Command Window (PC or UNIX)
Extracting Unencrypted I/Q Data
get /user/waveform/<file_name>
get /user/markers/<file_name>
get /user/header/<file_name>
Extracting Encrypted Waveform Data
get /user/securewave/<file_name>
Using Microsoft’s Internet Explorer thru FTP
1. Enter the signal generator’s hostname or IP address as part of the FTP URL.
ftp://<host name> or
ftp://<IP address>
2. Press Enter on the keyboard or Go from the Internet Explorer window. The signal generator files appear in the Internet
Explorer window.
3. Drag and drop files between the Internet Explorer window and the PC using the folder names below.
Extracting Unencrypted I/Q Data
get /user/waveform/<file_name>
get /user/markers/<file_name>
get /user/header/<file_name>
Extracting Encrypted Waveform Data
get /user/securewave/<file_name>
