ESG Family Signal Generators Using Functions
If You Encounter a Problem
User’s Guide 2-19
Signal Generator is Locked Up?
If your signal generator is locked up, try the following suggestions for resolution:
• Make sure that the signal generator is not in remote mode. (The
R annunciator will be
turned on in the display.) Press
Local to halt remote mode and return to listen mode.
• Make certain that the signal generator is not in a local lockout condition.
• Check for a progress bar on the signal generator display which indicates that an
operation is in progress.
• Try an instrument preset.
• Try cycling power.
If none of the previous suggestions resolves the problem, you can try the fail-safe recovery
sequence. This sequence should only be used as a last resort as it will reset the signal
generator but the process will destroy all user files (instrument state, sequence files, data
files), calibration data (unsaved I/Q calibrations, DCFM/DC
Φ
M calibrations), and the
persistent state. Do not attempt to perform any other front panel or remote operations
during the fail-safe sequence.
To run the fail-safe sequence, hold down the
Preset key while cycling power. Continue to
hold down the
Preset key until the ESG fail-safe recovery sequence message is displayed.
CAUTION Carefully read the entire message! It may list additional risks with the
procedure beyond what is documented here.
Release the
Preset key and press Yes to continue with the sequence (or No to abort with no
lost files).
At the conclusion of the sequence, perform the following steps:
1. Cycle power once again. Cycling power restores all previously installed options. You
should expect to see several error messages resulting from calibration files being
restored from EEPROM.
2. Perform the DCFM/DC
Φ
M calibration. (Refer to the
DCFM/DCΦM Cal softkey description
in Chapter 4, “Hardkey and Softkey Reference,” in this manual.)
3. For ESG-D and ESG-DP series signal generators only, perform the I/Q calibration.
(Refer to the
I/Q Calibration softkey description in Chapter 4, “Hardkey and Softkey
Reference,” of this manual.)
4. Agilent Technologies is interested in the circumstances that caused you to have to
initiate this procedure. Please contact us at 1-800-452-4844. We’d like to help you
eliminate any repeat occurrences.
